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.

Algebra 
Steve,
if x was invested at 9%, then 2900x was invested at 5%.
.09x + .05(2900x) = 217
x = 1800
so, $1800 at 9%, $1100 at 5%
