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?


f(n) = 19n + 5

f(n) = 5n + 9

f(n) = 4n + 29

f(n) = 5n + 29

Answer: f(n) = 5n + 9


Step-by-step explanation:

Given: A video game club charges a fixed annual membership fee of $19 and $5 per video game rented.

If the membership was decreased by $10 the next year them the charges for membership=$19-$10=$9

If n is the number of video games rented then the total annual cost of renting n video games=\(f(n)=9+5\times\ n\)

Thus the right answer is f(n) = 5n + 9, which best represents the relationship between f(n) and n if the membership was decreased by $10 the next year

Answer:

B
