Mr. Malone is putting money in two savings accounts. Account A started with $200 and Account B started with $300. Mr. Malone deposits $15 in Account A and $10 in Account B each moth. In how many months will the accounts have the same balance? What will that balance be?

Answer 1

you take $200 and add 15 and $300 and add 10 until the two # are the same.

Answer 2

200 + 15N = 300 + 10N.
5N = 100
N = 20 mo.
