Question

One month also rented 5 movies and 3 video games for a total of $31 the next month he rented 7 movies and 9 video games for a total of $71 find the rental cost for each movie and each video game

Answer 1

Answer:

V = 5.75, M = 0.45

Step-by-step explanation:

5M + 3V = 31

7M + 9V = 71

5M = 31 - 3V

M = (31 - 3V) / 5

7((31 - 3V) / 5) + 9V = 71

(217 - 21V)/5 + 9V = 71

43.4 - 4.2V + 9V = 71

4.8V = 27.6

V = 5.75

5M + 3(5.75) = 31

5M = 2.25

M = 0.45
