    Answer: George needs to work 12 hours to have enough money to buy the bicycle.

    Step-by-step explanation

    Needs $140

    Saved $44

    Makes $8hr

    Step One: Make an equation

    8h + 44 = 140

    Step Two: Solve for h

    8h + 44 = 140

    -subtract 44 on both sides'

    8h = 96

    -divide 8 on both sides

    h = 12

    Step Three: Check your work

    8h + 44 = 140

    8 (12) + 44 = 140

    96 + 44 = 140

    140 = 140
