Question

1. a website subscription costs $15 monthly plus a one - time setup fee of $20. write the equation for the total cost c for n months.

a. $c = 15n + 20$
b. $c = 35n$
c. $c = 20n + 15$
d. $c = 20 - 15n$

Explanation:

Step1: Identify monthly cost

The monthly cost is $15, so for \( n \) months, the monthly cost part is \( 15n \).

Step2: Add one - time setup fee

There is a one - time setup fee of $20. So the total cost \( C \) is the sum of the monthly cost for \( n \) months and the setup fee. That is \( C = 15n+20 \).

Answer:

a. \( C = 15n + 20 \)
