Answer: A

Step-by-step explanation:

Distribute 3x^2 into (x +9) first:

3x^2 × x = 3x^3

3x^2 × 9 = 27x^2

Next distribute 7 into (x+9):

7 × x = 7x

7×9 = 63

Add any like terms (none in this problem)

3x^3 + 27x^2 + 7x + 63

A) Because the 80 is by itself that would be the start up fee.

B) We are told x is the number of months. Since the X is being multiplied by 30, we know that would be the total monthly cost. This is being added to the 80, which does not have an exponent, so we know this is a single cost, which would be the start up fee.

C) Copying the same format as the given equation above, change the numbers:

f(x) = 20 + 35x

D) I used the same format as the first equation, which meant replacing the start up cost from the original one ( 80) with the start up of the new one (20). Then I changed the monthly cost from the original one (30) with the monthly cost of the new one (35).

E) Replace x in each equation with 8 and calculate the cost of each:

80 + 30(8) = 80 + 240 = $320

20 + 35(8) = 20 + 280 = $300

The second club (club B) is the cheaper option for her.
