Jim currently has $1,250$inhisbankaccountandSallyhas$1,400$ in her bank account. Jim deposits $27.50$perweekandSallydeposits$20$ per week into her account. After how many weeks will they have the same amount of money?
1250 + 27.50 W = 1400 + 20W
(27/50 - 20)W = 1400 -1250
7.50W = 150
W = 150 / 7.50 = 20 (weeks)
