Answer:
Cost 0.70 per pound.
Step-by-step explanation:
If you see the cost and the weight you can get the price per pound, so if 5 pounds cost $3.50, you can evaluate doing a rule of three:
[tex]\frac{3.50}{5}=\frac{x}{1}[/tex]
So if you clear X you´d get this:
[tex]x=\frac{(3.5)(1)}{5}[/tex]
[tex]x=0.70[/tex]
So the cost per pound is $0.70.
Now that you have the cost per pound you can do the equivalent ratios:
Cost---------------Apples
0.70---------------1 pound
3.5--------------- 5 pounds
7--------------- 10 pounds
Answer:
0.70 per pound.
Maria and Edwin have $23.00 each to spend at a book fair, where all students receive a 25% discount. They both want to purchase a copy of the same book, which normally sells for $26.50 plus 10% sales tax. To check if she has enough to purchase the book, Maria takes 25% of $26.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Edwin takes 75% of the normal purchase price and then computes 110% of the reduced price. Is Maria correct? Is Edwin correct? Do they have enough money to purchase the book? Explain your answer using complete sentences, and show your work.

@SignoraPenguino
Answer:
Step-by-step explanation:
They are both correct, the only difference is Maria did a two step process and Edwin did a one step process the total amount it would cost is $21.87 with $1.13 left over.
The way Maria calculates the final price of the book is correct. We know that the book normally sells for $26.50 plus a 10% sales tax. We also know that the students will receive an additional 25% discount. We must understand that the sales tax is applied to the discounted price. So first we will calculate 25% of 26.50 and subtract it from that amount. So the price will then be: (26.50 - 6.625). The price is now $18.34. Then to calculate the tax, it will be (10% * 18.34), so 1.834. We add this amount to the discounted price so: (18.34+1.834) = 20.12.
The final price of the book is $20.12 and Maria can get it and still save a little money.

When finding 433 - 249 using place value. What do you subtract first?
Final answer:
To subtract 433 - 249 using place value, start with the units place, proceed to the tens, and then the hundreds, borrowing as needed.
Explanation:
When finding 433 - 249 using place value, you should subtract starting with the rightmost digits, which are the units, and proceed to the left towards higher place values such as tens and hundreds, if necessary. This means you subtract the ones place first (3 - 9), then the tens place (3 - 4), and finally the hundreds place (4 - 2), borrowing from the next higher place value whenever the top digit is smaller than the bottom digit.

Acelynn borrows $1337 to buy a four wheeler. The interest rate is 4% for the 14 year loan.
Final answer:
Acelynn will pay back a total of $748.72 in interest over the 14 years of her loan for the four-wheeler. This was calculated using the simple interest formula.
Explanation:
To calculate how much interest Acelynn will pay back on the money borrowed for the four-wheeler, we use the simple interest formula: Interest (I) = Principal (P) × Rate (R) × Time (T).
Here, the principal P is $1337, the rate R is 4% (or 0.04 as a decimal), and the time T is 14 years.
Plugging these values into the formula, we get:
I = $1337 × 0.04 × 14
I = $53.48 × 14
I = $748.72
Therefore, as per the above explaination,Acelynn will pay back $748.72 in interest over the 14 years of the loan.
What is the distributive property of 48 + 72?
Answer:
12(4+6)
Explanation:
To write a problem using the distributive property, we must find a factor they have in common.
48 and 72 are both divisible by 12; this means that we can "pull out" 12. This will be what we multiply by in the distributive property.
48/12 = 4 and 72/12 = 6; this means this is what goes inside parentheses. This gives us
12(4+6)
The distributive property is expressed as 24 (2 + 3) = 24(2) + 24(3)
The distributive property is a property of multiplication used in addition and subtraction. In our case it is used in addition.
The property can be express mathematically as follows.
a(b + c) = ab + acTherefore,
lets find the factor of 48 and 72 to represent the distributive property.

The y-intercept of the exponential function is _______ the y-intercept of the linear function.
Answer: The y-intercept of the exponential function is approximately 2000 less than the y-intercept of the linear function.
Step-by-step explanation:
Given: The exponential function in the table represents the student population of the county that Greenville is in, in years since 2010.
The standard exponential function is given by :-
[tex]y=Ab^x[/tex], where A is the initial population and x is the number of years.
From table , the multiplicative rate of change b=[tex]\frac{y_3}{y_2}=\frac{4400}{2200}=2[/tex]
Put x=2 and b=2 in the equation, we get
[tex]2200=A(2)^2\\\Rightarrow\ A=\frac{2200}{4}=1950[/tex]
We know that the value of y intercept occurs when x=0,
From the given table , the y intercept of exponential function (Initial population)= 550
The linear function in the graph shows the population of Greenville in the years since 2010.
From the given graph, the y intercept of linear function (x=0 for year 2010)= 2500
The difference in y intercepts = [tex]2500-550=1950\approx2000....\text{{Rounded nearest thousand}}[/tex]
Hence, The y-intercept of the exponential function is approximately 2000 less than the y-intercept of the linear function.
A grocer sells eggs only in boxes of 8. If he starts with 175 eggs and fills as many boxes as he can with eggs, how many eggs will he have left over?
After dividing the total number of eggs (175) by the number of eggs per box (8), the grocer will have 7 eggs left over once 21 boxes are filled.
Explanation:To solve how many eggs the grocer will have left over, we need to divide the total number of eggs (175) by the number of eggs in a box (8).
Divide 175 by 8 which equals 21 with a remainder of 7.Therefore, the grocer can fill 21 boxes with 8 eggs each.The grocer will have 7 eggs left over.This calculation involves basic division and understanding remainders, which are common math skills taught in middle school.
The grocer starts with 175 eggs and sells them in boxes of 8. To find the number of boxes he can fill, we divide the total number of eggs by the number of eggs per box: 175 / 8 = 21.875. Since the grocer can only sell whole boxes, he can fill 21 boxes. To find the number of eggs left over, we subtract the number of filled boxes from the total number of eggs: 175 - (21 * 8) = 175 - 168 = 7 eggs left over.

A geologist had two rocks on a scale that weighed 3.3 kilograms together. Rock A was 0.1 of the total weight. How much did rock A weigh?
Answer:
Rock A had a weight of 0.33Kg
Step-by-step explanation:
Let X: the weight of rock A and Y: the weight of rock B. The information available suggests that:
X + Y = 3.3 [Eq. one]
X = 0.1 (X + Y) [Eq. two]
Considering equation 2, we have that X = 0.1X + 0.1Y, which produces:
0.9X = 0.1Y ------------> 9X = Y. Substituting this last result in equation 1, you have:
X + 9X = 3.3, that is,
10X = 3.3 --------> X = 3.3 / 10 = 0.33Kg. As Y = 9X, then, Y = 9 (0.33) = 2.97Kg
