An equation for this problem- The cable company charges a monthly fee of $45. Each movie rental is $1.99. You owe $68.88/ How many movies did you rent?
Answers
Answer:
12 movies
Step-by-step explanation:
If you have to pay 1.99 per movie and that is our unknown, we can express that as 1.99x, where x is the number of movies (our independent variable). If you rent 0 movies, you still have to pay the company $45. So the equation for the number of movies you rent:
y = 1.99x + 45 where y is the total cost of your cable for that month. We know the cost for a certain month was 68.88 so our equation becomes
68.88 = 1.99x = 45 and
23.88 = 1.99x so
x = 12 movies
To calculate the number of movies you rented, first subtract the monthly fee of $45 from the total amount owed of $68.88, which leaves $23.88 for movie rentals. Since each movie costs $1.99, divide $23.88 by $1.99 to get approximately 12 movies rented.
Explanation:
The subject of this question is a simple algebraic problem involving a basic equation. To find out how many movies were rented, we first need to understand what charges make up the total charge of $68.88. Given that the cable company charges a monthly fee of $45 and each movie rental costs $1.99, we know that the total charge of $68.88 includes both the monthly fee and the cost of movie rentals.
To find out how many movies were rented, we subtract the monthly fee from the total owed: $68.88 - $45 = $23.88. This is the total cost for movie rentals. Since each movie costs $1.99, we divide the total cost of rentals by the cost per movie: $23.88 / $1.99. The answer is about 12, "so you rented approximately 12 movies".

what are the two types of exponential functions?
Answers
The two types of exponential functions are:
Exponential Growth: exponential growth function is [tex]y = a^x[/tex], where "a" is the base and "x" is the exponent.
Exponential Decay: exponential decay function is [tex]y = a^{(-x)[/tex], where "a" is the base and "x" is the exponent.
The two types of exponential functions are:
Exponential Growth: In an exponential growth function, the base (often denoted by "a") is greater than 1.
As the input (x) increases, the output (y) grows at an increasing rate, creating a steep upward curve on the graph.
The general form of an exponential growth function is [tex]y = a^x[/tex], where "a" is the base and "x" is the exponent.
Exponential Decay: In an exponential decay function, the base (often denoted by "a") is between 0 and 1 (exclusive).
As the input (x) increases, the output (y) decreases at an increasing rate, creating a steep downward curve on the graph.
The general form of an exponential decay function is [tex]y = a^{(-x)[/tex], where "a" is the base and "x" is the exponent.
Both types of exponential functions show rapid growth or decay patterns, and their graphs exhibit a characteristic curve that is continuous and smooth.
The difference lies in the behavior of the output (y) concerning the input (x).
In exponential growth, the output increases exponentially with increasing input, while in exponential decay, the output decreases exponentially as the input increases.

A refrigerator is priced at $1,250. There are two options offered to reduce the price: either a 25% discount off the price or a rebate of $300. Which is the better choice, and what is the extra amount saved?
A.The 25% discount is better; it saves $12.50.
B.The rebate is better; it saves $12.50.
C.The 25% discount is better; it saves $75.
D.The rebate is better; it saves $75.
Answers
Answer:
A.The 25% discount is better; it saves $12.50.
Step-by-step explanation:
Here, the given marked price of the refrigerator = $ 1250,
In first option,
Discount percentage = 25 %,
Thus, total discount = 25 % of the marked price
= 0.25 × 1250
= 312.5
Thus, the selling price = 1250 - 312.5 = $ 937.5,
In second option,
Discount = $ 300,
Thus, the selling price = 1250 - 300 = $ 950,
Since, 937.5 < 950
Hence, First option is better than that of second.
Also, total saving = 950 - 937.5 = $ 12.5
⇒ The 25% discount is better; it saves $12.50

Answer:

a) production level at max revenue = 2850
b) price to max profit = $125
c) Suppose that a 5 dollar per drill tax is imposed. Determine the number of drills that should be produced and sold in order to maximize profit under these new circumstances. ???
Answers
Revenue x * p = 220x - x^2/30
d/dx = 220 * 15 = 3300
B.
Profit = Revenue - Cost
= 220x - x^2/30 - 72000 - 80x
d/dx = 220 - x/15 - 80 = 0
x = 15 * 140 = 2100
p = 220 - 2100/30 = 220 - 70 = $150
C.
With $5 tax the price-demand equation should be
p = 220 - x/30 + 5
Profit = 225x - x^2/30 - 72000 - 80x
d/dx = 225 - x/15 - 80 = 0
x = 15 * 145 = 2175

A shopper purchased 8 T-shirts and 5 pairs of pants for $220. The next day he purchased 5 T-shirts and 1 pair of pants for $112. How much does each T-shirt and each pair of pants cost?
Answers
5t + p = 112....multiply by -5
----------------
8t + 5p = 220
-25t - 5p = - 560 (results of multiplying by -5)
---------------add
- 17t = - 340
t = 340/17
t = 20 <== each tee shirt costs $ 20
8t + 5p = 220
8(20) + 5p = 220
160 + 5p = 220
5p = 220 - 160
5p = 60
p = 60/5
p = 12 <== each pair of pants cost $ 12
By setting up a system of linear equations based on the shopper's purchases and solving it, we found that the cost of each T-shirt is $20, and the cost of each pair of pants is $12.
Explanation:To find out how much each T-shirt and each pair of pants cost based on the shopper's purchases, we can set up a system of linear equations. Let's denote the cost of a T-shirt as T and the cost of a pair of pants as P.
The two purchases give us these equations:
8T + 5P = $220
5T + 1P = $112
Next, we use a method such as substitution or elimination to solve these simultaneous equations. If we multiply the second equation by 5, we get:
5(5T + 1P) = 5($112)
25T + 5P = $560
Now subtract the first equation from this result:
25T + 5P - (8T + 5P) = $560 - $220
17T = $340
T = $20
Now that we know the cost of a T-shirt, we can substitute T in one of the original equations to find P:
5T + P = $112
5($20) + P = $112
$100 + P = $112
P = $12
So, a T-shirt costs $20 and a pair of pants costs $12.

A unit of measure used in surveying is the link; 1 link is about 8 inches. about how many links are there in 9 feet.
Answers
1 link = 8 inches
1 inch = 0.083 feet
108 inches = 9 feet
To find how many links:
108/8= 13.5 links
To find out how many links are there in 9 feet, we can use the conversion factor that 1 link is about 8 inches.
Explanation:To find out how many links are there in 9 feet, we can use the conversion factor that 1 link is about 8 inches. First, we need to convert 9 feet to inches by multiplying it by 12 (since there are 12 inches in 1 foot). So, 9 feet = 9 x 12 = 108 inches. Next, we can divide 108 inches by 8 (since 1 link is approximately 8 inches) to find the number of links. 108 inches ÷ 8 = 13.5 links. Therefore, there are approximately 13.5 links in 9 feet.
