After Joel deposits $25.50 into his savings account, his balance is $275.00. Which equation can be used to find the amount, n, in his account before he made the deposit?
We know that Joel deposited $25.50, and now his total is $275.00. That is the "whole". So to find n, the amount BEFORE the $25.50, we have to subtract: n=$275.00-$25.50. n=$249.50 :)
