Question

A video game club charges a fixed annual membership fee of $18 and $3 per video game rented. Let f(n) represent the total annual cost of renting n video games. Which of the following functions best represents the relationship between f(n) and n if the membership was increased by $20 the next year?

f(n) = 18n + 38

f(n) = 38n + 18

f(n) = 3n + 38

f(n) = 3n + 18

Answer 1

I believe the third one
18 + 20 = 38
3n represents the 3 dollars multiplied by the amount of videos
so total {f(n)] is 3n + 38
