Question

1. (04.02 mc) a video game club charges a fixed annual membership fee of $19 and $5 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 decreased by $10 the next year? (5 points) \bigcirc f(n) = 19n + 5 \bigcirc f(n) = 5n + 9 \bigcirc f(n) = 4n + 29 \bigcirc f(n) = 5n + 29

Explanation:

Step1: Calculate new fixed fee

$\$19 - \$10 = \$9$

Step2: Define total cost function

Total cost = (cost per rental $\times$ number of rentals) + fixed fee
$f(n) = 5n + 9$

Answer:

C. $f(n) = 5n + 9$
