WILL MEDAL! 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 = the number of nights Michelle has the movie. A) c(x) = 1.50 + 1.25x B) c(x) = 1.50x + 1.25 C) c(x) = 2.75 D) c(x) = (1.50 + 1.25)x

    yes, and now, since it's the only value that varies, we can say for sure that the first 1.50 are the initial ones, so thereby: \[f(x)=1.50+1.25x\] Where "x" represents the nights she has the movie.
