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. (2 points)

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

Answer:

First option

Step-by-step explanation:

Michelle rents a movie for a flat fee of $1.50 plus an additional $1.25 for each night she keeps the movie.

Here, we want to create a function that represents the total cost if x = # of nights Michelle has the movie.

We know that she pays a one time flat fee of $1.50 so we start off with

c(x) = ?x + 1.50

We also know that she pays 1.25 for EVERY night she keeps the movie.

So cost of movie after x nights equals 1.25x

So total cost would equal c(x) = 1.25x + 1.50
