A person invests $4500.oo into 2 different mutual funds. The first has a 4.5% interest rate the second 6%. He made a total of $225 in the investment. How much did he invest in each fund?

Answer 1

Invested $X @ 4.5%.
Invested $(4500-X) @ 6%.
Investment assumed to be for 1 year.

.045x + 0.06(4500-x) = $225.
.045x + 270 - 0.06x = 225
-0.015x = 225 - 270 = -45
X = $3000 @ 4.5%.
4500-x = 4500-3000 = $1500 @ 6%.
