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
