Question

One month Ivanna rented 2 movies and 6 video games for a total of $42. The next month she rented 5 movies and 3 video games for a total of $30 . Find the rental cost for each movie and each video game.

Answer 1

2M + 6V = 42

M + 3V =21

5M+15V = 105

5M + 3V = 30

12V = 75

V = 75/12 = $6.25 for a video

M= 21-3(6.25) = 21-18.75 = $2.25 for a movie
