Question

Jaclyn has $120 saved and earns $40 each month in allowance. Pedro has $180 saved and earns $20 a month in allowance.

If they both save their entire allowances, how long will it take before Jaclyn and Pedro have saved the same amount of money?
Enter your answer in the box

Answer 1

3 months

Explanation:

120 + 40m = 180 + 20m

Collect like terms

40m - 20m = 180 - 120

20m = 60

Divide

m = 60/20

m = 3

It will take them 3 months before Jaclyn and Pedro have saved the same amount of money.
