Question 1189556
<br>
Here is a quick and easy informal way to solve a "mixture" problem like this.<br>
(1) $590 interest on an investment of $10,000 is a return of 5.9%
(2) 5.9% is 9/10 of the way from 5% to 6%
(3) That means 9/10 of the total was invested at the higher rate.<br>
ANSWER: 9/10 of the $10,000, or $9000, at 6%; the other $1000 at 5%.<br>
CHECK: .06(9000)+.05(1000)=540+50=590<br>
