Question 283771
<br>
$900 interest on an investment of $10,000 is a rate of return of 9%.<br>
9% is three-fifths of the way from 6% to 11%; that means 3/5 of the total was invested at the higher rate. (If it helps, look at the three percentages 6, 9, and 11 on a number line.)<br>
3/5 of $10,000 is $6000.<br>
ANSWER: He invested $6000 in the mutual fund (and $4000 in the CD)<br>
