Question

Michelle rents a movie for a flat fee of $1.50 plus an additional $1.25 for each night she keeps the movie. Choose the cost function that represents this scenario if x equals the number of nights Michelle has the movie.

A) c(x) = 1.50 + 1.25x
B) c(x) = 1.50x + 1.25
C) c(x) = 2.75
D) c(x) = (1.50 + 1.25)x

Answer 1

the answer would be A

Answer 2

A) c(x)=1.50+1.25x

Explanation:

The fixed rate (constant) is 1.50 and 1.25 (variable) depending on the number of additional nights, that is, c (x) = 1.25 (x) +1.50 =1.50+1.25x
