It cost $5 to become a member of a video game club. After that, video games are 10 each with a 7% tax on each game. If you spend $69.20 TOTAL, how many video games did you buy?

Answer: you bought 6 games.

Step-by-step explanation:

Let x represent the number of video games that you bought.

Each video game costs $10. The cost of x video games would be $10x. There is a 7% tax on each game. It means that the amount of tax on x games would be

7/100 * 10x = $0.7x

It cost $5 to become a member of a video game club. It means that the total amount he paid for x video games is

5 + 10x + 0.7x

= 5 + 10.7x

If you spend $69.20 total, it means that

5 + 10.7x = 69.2

10.7x = 69.2 - 5

10.07x = 64.2

x = 64.2/10.7

x = 6
