Question

Angie is saving money for a new bike. She has 2/3 of the amount of money she needs for the bike. She has $120 saved. How much does the bike cost?

Answer 1

If Angie has 2/3 of the amount of money a new bike costs, and she has $120 saved for the bike, then the total cost of the new bike is $180.

If she already has 2/3 of the money saved, then we could divide $120 by 2 to see the rate of change. In this case, the rate of change is $60. Then, we could multiply $60 by 3 to get $180, which is the cost of the bike.
