B) c(x) = 1.50x + 1.25
C) c(x) = 2.75
D) c(x) = (1.50 + 1.25)x

Best ResponseYou've already chosen the best response.1yes, 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.
