An investor invested a total of $1400 in two mutual funds. One fund earned a 6% profit while the other earned a 2% profit. If the investor's total profit was $72, how much was invested in each mutual fund?

Answer 1

add up the interest earned:

.06x + .02(1400-x) = 72
x = 1100

so, 1100 at 6% and 300 at 2%
