Word problem math

Lee worked 22 hours this week and made $132. If she works 15 hours next week at the same pay rate, how much will she make?

  • Word problem math -

    Set up a proportion and cross multiply.

    22/132 = 15/x

  • Word problem math -

    ok that is the equation that I had got as well but how do I cross multiply?

  • Word problem math -

    Multiply the first and last terms together. Then multiply the middle two terms together.

    22/132 = 15/x
    22x = 132 * 15
    22x = 1980
    x = 90

    You could also find her hourly wage for the 22-hour week and apply it to her 15-hour week.
