    A carnival charges a $15 admission price. Each game at the carnival costs $4. How many games would a person have to play to spend at least $40?

    Let g be the number of games. The Spend function S(g) is:
    S(g) = Cost per game * number of games + admission price
    S(g) = 4g + 15

    The problem asks for g when S(g) is at least 40. At least is an inequality using the >= sign:
    4g + 15 >= 40

    To solve this inequality for g, we type it in our search engine and we get:
    g >= 6.25

    Since you can't play a partial game, we round up and get:
    g >= 7
