(30 points) jamie rents a movie for a flat fee of $2.50 plus an additional $0.75 for each night she keeps the movie. choose the cost function that represents this scenario if x equals the number of nights jamie has the movie. c(x) = 2.50x + 1.25 c(x) = 3.25 c(x) = 2.50 + 0.75x c(x) = (2.50 + 0.75)x

c(x) = 2.50 + 0.75x

Step-by-step explanation:

She pays 2.50 for the movie, that number won't change. Every night she keeps the movie it's an additional 0.75, we do not know how many night she is going to keep it, therefore we place x.

C: c(x) = 2.50 + 0.75x
