Julie spent $50 on a book. The cost of the book was $24 less than twice what she spent on a backpack. How much did the backpack cost?.

  • math -

    "The cost of the book was $24 less than twice what she spent on a backpack"
    or
    book = 2(backpack) - 24
    50 = 2backpack-24
    74 = 2backpack
    37 = backpack

    check:
    twice cost of backpack = 74
    Is 50 less than 74 by 24 ? YES!
