an investor invested a total of $2,900 in two mutual funds. One fund earned a 7% profit while the other earned a 2% profit. If the investor's total profit was $108, how much was invested in each mutual fund?

Answer 1

invested at 7% --- x
invested at 2% ---- 2900-x

solve for x

.07x + .02(2900-x) = 108
times 100
7x + 2(2900-x) = 10800

take it from there.
