Question

A combined total of $41,000 is invested in two bonds that pay 6% and 9.5% simple interest. The annual interest is $3,300.00. How much is invested in each bond?

Answer 1

.095x+.06(41-x)=3.3

.035x =3.3-2.46=.84

x=.84/.035= 840/35=168/7=24

=$24,000 invested at 9.5%

$17,000 at 6%

.095(24)+.06(17)=2.28+1.02=3.3

3.3/41=average return of about 8.1%

8.1-6=2.1

9.5-8.1 = 1.4

1.4/2.1 =about .7

17/24 = about. .7
