Answer 1

The correct representation of each part of the function is:

y is the total cost, x is the number of months of service, $99 is the service charge per month, and $15 is the one-time installation fee.

The function y = 99x + 15 shows that the cost (y) is dependent on the number of months of service (x). The monthly service charge is multiplied by the number of months (99x), and the one-time installation fee ($15) is added to this product to give the total cost.
