You invested \$14,000 in two accounts paying 5% and 9% annual interest, respectively. If the total interest earned for the year was \$820, how much was invested at each rate?

• Math -

If you have x at 5%, then you have (14000-x) at 9%. Now just calculate the interest on each and add it up:

.05x + .09(14000-x) = 820
x = 11000

so, you have \$11,000 at 5% and \$3000 at 9%.
