Question 1081160: if you invest a total of $42,000 in three different bank accounts. one account pays an annual interest rate of 3%, the second account pays 4% annual interest, and the third account pays 5% annual interest. in one year, you earned a total of $1740 in interest from these three accounts. if you invested $15000 more in the account that pays 4% interest than she did in the account that pays 5% interest, find the amount you invested in each account Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! x at 4%
x-15000 at 5%
57000-2x at 3%
.03(57000-2x)+.04x+.05(x-15000)
1710-.06x+.04x+.05x-750=1740
.03x=780
x=$26000@4%=$1040
x-15000=$11000@5%=$550
57000-2x=$5000@3%=$150
They add to $1740.
