Question

One month ali rented 5 movies and 3 games for a total of $36. The next month he rented 7 movies and 9 games for a total of $78. Find the rental cost for each mcoie and each video game

Answer 1

`m = 3.75`

Explanation:

`5m + 3g = 36 \\ 7m + 9g = 78`

Make it so that one of the values is the same

`15m + 9g = 108 \\ 7m + 9g = 78`

Take them away from each other

`8m = 30 \\ m = 3.75`
