Question

Chang rented some movies and video games last month. He did the same this month. The table below shows the number of movies and video games ne renter each month. It also shows the total cost (in dollars).

Answer 1

See below

Explanation:

Cost of movie => x

Cost of video game => y

5x + 3y = 24

2x + 12y = 69 or 34.5-6y = x

Substitute

5x + 3y = 24

5(34.5-6y) + 3y = 24

172.5 - 30y + 3y = 24

-27y = -148.5

y = 5.5

34.5-6y = x

34.5-6(5.5) = x

x = 1.5
