let the amount invested at 6% be x
then the amount at 7% is 2x
let the amount invested at 4% be y
so x + 2x + y = 24900
y = 24900 - 3x
.06x + .07(2x) + .04(24900-3x) = 1412
proceed as before
and investor has a total of $24,900 deposited in three different accounts which earn annual interest rate of 7% 6% and 4%. the amount deposited in the 7% account is twice the amount in the 6% account. if the three accounts earn a total annual interest of $1412 how much money is deposited each account
