    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
