Question 32085
Let amount invested at 9% be "x"
Then amount invested at 10% must be "x+500"
Interest on the 9% investment is 0.09x
Interest on the 10% investment is .10(x+500)=0.10x+50
EQUTION:
Interest + Interest = $183
0.09x + 0.10x+50 = 183
9x + 10x + 5000 = 18300
19x= 13300
x=$700 (amount invested at 9%)
x+500= $1200 (amount invested at 10%)
