Algebra 1 honors 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.

c(x) = 1.50 + 1.25x

c(x) = 1.50x + 1.25

c(x) = 2.75

c(x) = (1.50 + 1.25)x
