Question

Michelle rents a movie for a flat fee of $1.50 plus an additional $1.25 for each night she keeps the movie. If Michelle keeps the movie for 3 nights, how much will she pay when she returns it?

Answer 1

Usually problems like this can be written in the form of \[mx+b=y\] In this case, the rate would be your slope (m) and the flat fee would be b. If you plug in the numbers, you'd get \[1.25(3)+1.50=y\] The answer is $5.25
