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

Well, its 1.25 for each night so that can represent any number suppose she goes 10 nights.
1.25(10)

and its has a flat fee of 1.50 so regardless, she'll have to pay 1.50 every time

okay.... (lol im copying the steps down), is that all i need ti  do?

anonymous · Answer

think about it,,,if x represents the number of nights....and 1.50 is a set fee, and 1.25 per night...to figure the total you need 1.50 + 1.25x. Does that make sense ? Because you are not paying 1.50 per night.
