    Jake is 60 years old. Lucy is ten years older than Max. If Lucy's and Max's age combined is half Jakes age, what is Lucy's age?

    Jake = 60

    Lucy = x + 10

    Max = x years old

    x + x + 10 = (1/2)(60)

    2x + 10 = 30

    2x = 30 - 10

    2x = 20

    x = 20/2

    x = 10

    Lucy's age = x + 10

    Lucy's age = 10 + 10

    Lucy's age = 20 years old.

    I like age word problems. Of course, this is an easy sample.
