Question

An investor invested a total of ​$2 comma 500 in two mutual funds. One fund earned a 9​% profit while the other earned a 6​% profit. If the​ investor's total profit was ​$171​, how much was invested in each mutual​ fund?

Answer 1

0.09x+0.06 (2500-x)=171

solve for x

0.09x+150-0.06x=171

0.03x+150=171

0.03x=171-150

0.03x=21

X=21÷0.03

X=700 invested at 9%

2500-700=1800 invested at 6%

Hope it helps!
