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.

Answer 1

1.50 + 1.25x = c (which can mean the total money she has to pay)

Answer 2

Answer: The required function would be,

`C(x)=1.50+1.25x`

Explanation:

Given,

Flat fee for renting the movie = 1.50,

Also, for each night the addition charges = $ 1.25,

⇒ For x nights the additional charges = 1.25x,

Thus, the charges for a renting the movie for x nights = Flat fee + Additional charges

= 1.50 + 1.25x

Let C(x) represents the cost,

⇒ C(x) = 1.50 + 1.25x

Which is the required function.
