Question

Helps Pleasee DX
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.

-c(x) = 1.50 + 1.25x
-c(x) = 1.50x + 1.25
- c(x) = 2.75
-c(x) = (1.50 + 1.25)x

Answer 1

Flat fee would be the constant...
1.25 is a variable because we dont know how many nights she will have it...so this is 1.25x

So we have c(x) = 1.25x + 1.50
