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?

invested at 7%  x
invested at 2%  2900x
solve for x
.07x + .02(2900x) = 108
times 100
7x + 2(2900x) = 10800
take it from there.
