Question

Bill weighs 120 pounds and is gaining ten pounds each month. Phil weighs 150 pounds and is gaining 4 pounds each month. How many months, m, will it take for Bill to weigh the same as Phil? *

Answer 1

5 months

Explanation:

120 * 10m = 150 * 4m

subtract 4m to 10m

120 * 6m = 150

subtract 120 to 150

6m = 30

divide 6 to 30

30 / 6 = 5

5 months
