(03.02) Sarah rents a movie for a flat fee of $3.00 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 Laura has the movie. (2 points)
O c(x) = (3.00 +0.75)x
O c(x) = 3.00x + 0.75
c(x) = 3.00 +0.75x
O clx) = 3.75x
