Grace earns $7 for each car she washes. She always saves $22 of her weekly earnings. This week, she wants to have at least $63 in spending money. How many cars must she wash? Enter and solve an inequality to represent this situation. Enter your value as a simplified mixed number, if necessary.
Answers
Answer:
12 1/7 cars
Step-by-step explanation:
Let the number of cars she'd wash to earn $63 in spending money be A.
Given she saves $22 of her weekly earnings and wants to have at least $63 for spending money.
That means she’d have to make $63 + $22 = $85
The expression is thus
$85 = A x $7
Where A is the number of cars and $7 is the amount she earns for washing one car and $85 is the total amount she has to make .
Therefore,
85 = A x 7
Divide both sides by 7
85/7 = A x 7/7
12 1/7 = A
A = 12 1/7 cars
She must wash 12 1/7 cars to have at least $63 spending money and also have her weekly Savings of $22

Jim worked for three different employers. They each paid him $15 000. How much income tax should he have paid?
Answers
Jim's income tax liability for the $45,000 he earned from his three employers would be $9,500.
To calculate Jim's income tax, we first need to find his total income. Since he worked for three different employers, his total income would be the sum of his earnings from each employer, which is $15,000 * 3 = $45,000.
Next, we need to know the tax rates that apply to Jim's income. Income tax rates are usually progressive, meaning different portions of income are taxed at different rates.
Using the hypothetical tax rates mentioned above, we can calculate Jim's income tax liability:
First $10,000 at 10%: $10,000 * 0.10 = $1,000
Next $20,000 at 20%: $20,000 * 0.20 = $4,000
Remaining $15,000 at 30%: $15,000 * 0.30 = $4,500
Now, summing up the tax amounts from each tax bracket: $1,000 + $4,000 + $4,500 = $9,500.
Therefore, Jim's income tax liability should have been $9,500.

Final answer:
Jim earned a total of $45,000 from three employers. Using a simplified marginal tax rate example, his total income tax comes to approximately $7,106.25. This calculation method demonstrates how the marginal tax rate system works in a basic form.
Explanation:
To determine how much income tax Jim should have paid on his earnings from three different employers, where each paid him $15,000, we first need to calculate his total income. Jim's total income is $15,000 from each job, multiplied by 3, because he worked for three different employers, resulting in a total income of $45,000.
Assuming a simple tax rate example (for illustrative purposes), let's use the marginal tax rates provided in the reference:
Income from $0 to $9,075 is taxed at 10%
Income from $9,075 to $36,900 is taxed at 15%
Income from $36,900 and beyond is taxed at 25%
Since Jim earns $45,000, here is how his taxes would be calculated:
The first $9,075 is taxed at 10%, amounting to $907.50.
The next $27,825 ($36,900 - $9,075) is taxed at 15%, amounting to $4,173.75
The remaining $8,100 ($45,000 - $36,900) is taxed at 25%, amounting to $2,025.
Add up these amounts to get the total tax:
$907.50 + $4,173.75 + $2,025 = $7,106.25
Therefore, applying this simplified tax calculation, Jim should have paid a total of roughly $7,106.25 in income tax on his total earnings of $45,000 from three different employers.

Erwin had 2 5/12 gallons of lemonade. He spilled 11/12 gallon of lemonade. How much lemonade dose he have left? Write in simplest form
Answers
Answer:
Erwin have 1 [tex]\frac{1}{2}[/tex] gallons of lemonade left
Step-by-step explanation:
Erwin had 2 5/12 gallons of lemonade. He spilled 11/12 gallon of lemonade. How much lemonade dose he have left? Write in simplest form
All we need to do is to subtract 11/12 from 2 5/12. But to do this, we will convert 2 5/12 to improper fraction
converting 2 5/12 to improper fraction yields : 29/12
Lemonade have left = Total lemonade - lemonade spilled
= 29/12 - 11/12
= 18/12
Lemonade have left =18/12
But we can reduce 18/12 to its lowest term
18÷6/ 12÷6 = 3/2
Lemonade have left = 3/2
We can change to 3/2 to a mixed number to give us 1 [tex]\frac{1}{2}[/tex]
Therefore Erwin have 1 [tex]\frac{1}{2}[/tex] gallons of lemonade left
Answer:
(3/2) or (1 1/2) gallons of lemonade
Step-by-step explanation:
Erwin had 2 5/12 gallons of lemonade at his disposal which also translate to 29/12 gallons.
If he spills 11/12 gallon of the lemonade,then the quantity left with him will be (29/12) - (11/12) = 18/12(change to proper fraction): 3/2 or 1 1/2 gallons of lemonade

Difference = $3
2. For the mean (as per the requirement in the image): the mean of TJ's earnings is more than the mean of Justin's earnings
Difference = $4
Explanation:
The complete question is shown in the attached image
1. The median:
It is defined as the value found in the middle of a set of arranged data/numbersIf the set has odd number of data, then the median is simply the middle valueIf the set has even number of data, then the median is the average of the two middle valuesTo get the median, we need to first arrange the given dataa. For Justin:
He earned the following: $32, $45, $50, $33 and $50
Arranging the data: $32, $33, $45, $50 and $50
The middle value is: $45
The median is: $45
b. For TJ:
He earned the following: $58, $48, $40, $42 and $42
Arranging the data: $40, $42, $42, $48 and $58
The middle value is: $42
The median is: $42
c. Comparing the medians:
From the above, we can conclude that the median of Justin's earnings is more than the median of TJ's earnings
Difference = $45 - $42 = $3
2. The mean:
It is defined as the average value of a set of dataIt is calculated by summing the values in the set and then dividing this sum by the number of vales in the seta. For Justin:
He earned the following: $32, $45, $50, $33 and $50
Summing the data: $32 + $33 + $45 + $50 + $50 = 210
Number of values in the data= 5
The mean is: [tex]\frac{210}{5}=42[/tex]
b. For TJ:
He earned the following: $58, $48, $40, $42 and $42
Summing the data: $40 + $42 + $42 + $48 + $58 = $230
Number of values in the data: 5
The mean is: [tex]\frac{230}{5} = 46[/tex]
c. Comparing the values:
From the above, we can conclude that the mean of TJ's earnings is more than the mean of Justin's earnings
Difference = 46 - 42 = $4

You buy a car for $8000 that depreciates (loses value) at a rate of 11% a year. How much is the care
worth after 5 years?
Answers
Answer:
$3600
Step-by-step explanation:
Cost of the car = $8000
The car loses value at 11% each year .
That’s
11% /100% x $8000
0.11 x 8000
$880
11% decrease each year means that the cost of the car is reduced by $880 per year.
Therefore,
Worth of the car in 5 years
= $8000 - ($880 x 5)
= $8000 - $4400
= $3600
The car will be worth $3600 in five years
: The You Move It Company (YMI) advertises that the cost to rent a moving truck for one day is $40 plus $1.99 for each mile the truck is driven.

Alex wants to rent a single truck to use on both Saturday and Sunday on a weekend. Part A For what driving distance does it not matter from which company Alex rents the truck? miles. If Alex only plans of driving 150 miles over the weekend, which company should he use? Part B Give a mathematical explanation as to how you arrived at your answer.
Answers
Part A: For 100 miles, the cost will be same for both companies.
Part B: Alex should use Drive and Move company as it will cost him less money.
Step-by-step explanation:
Given,
Starting amount of YMI= $40
Per mile charges = $1.99
Let,
x be the number of miles.
y be the total charges.
y = 1.99x+40 Eqn 1
Starting amount of DM = $60
Per mile charges = $1.79
y=1.79x+60 Eqn 2
Part A:
For same charges;
Eqn 1 = Eqn 2
[tex]1.99x+40=1.79x+60\\1.99x-1.79x=60-40\\0.20x=20[/tex]
Dividing both sides by 0.20
[tex]\frac{0.20x}{0.20}=\frac{20}{0.20}\\x=100[/tex]
For 100 miles, the cost will be same for both companies.
Part B:
Total miles = x = 150
Putting x=150 in Eqn 1
y=1.99(150)+40
y=298.5+40
y=$338.50
Putting x=150 in Eqn 2
y=1.79(150)+60
y=268.5+60
y=$328.50
Alex should use Drive and Move company as it will cost him less money.

On a sunny day around noon , a tree casts a shadow that is 12 feet long . At the same time , a person who is 6 feet tall standing beside the tree casts a shadow that is 2 feet long . How tall is the tree?
Answers
Answer:
36 ft. tall
Step-by-step explanation:
We can easily solve this problem with a simple proportion:
12 feet / height = 2 feet / 6 feet
6 * 12 = 2h
72 = 2h
h = 36 ft.
It's found that the tree is 36 feet tall.
To find the height of the tree using the lengths of the shadows and the person's height, we can use a proportion based on similar triangles. Since the sun's rays hit both the tree and the person at the same angle, the ratio of the height of the tree to the length of its shadow is the same as the ratio of the person's height to the length of their shadow.
Let's let 'h' represent the height of the tree. We can set up the proportion as follows:
Person's height / Person's shadow length = Tree's height / Tree's shadow length
6 feet / 2 feet = h / 12 feet
Now we solve for 'h' by cross-multiplying:
6 feet * 12 feet = 2 feet * h
72 feet2 = 2 feet * h
Divide both sides by 2 feet to get:
h = 36 feet
Therefore, the tree is 36 feet tall.

First distribute 3 into (1 - x)
We have
2x - 5 = 3 x 1 -3 x X + 22
2x - 5 = 3 - 3x + 22
The expression can be rearranged as
2x - 5 = 3 + 22 - 3x
2x - 5 = 25 - 3x
Add 3x to both sides
3x + 2x - 5 = 25 - 3x + 3x
5x - 5 = 25
Add five to both sides
5x - 5 + 5 = 25 + 5
5x = 30
Divide both sides by 5

[tex](\frac{7}{3} )\frac{3}{7}s=6(\frac{7}{3} )[/tex]
Simplifying the expression, we have,
[tex]s=\frac{42}{3}[/tex]
