An investor invested a total of 2900 in two mutual funds. One fund earned a 9% profit the other earned a 5% profit. If the investors total profit was $217 how much was invested in each mutual fund.

Answer 1

if x was invested at 9%, then 2900-x was invested at 5%.

.09x + .05(2900-x) = 217
x = 1800

so, $1800 at 9%, $1100 at 5%
