Question 911346
You have already invested $450 in a stock with an annual return of 11%. How much of an additional $1,200 should be invested at 12% and how much at 6% so that the total return on the entire $1,650 is 9%?
***
let x=amt invested at 12%
1200-x=amt invested at 6%
11%450+12%x+.06(1200-x)=9%*1650
49.50+.12x+72-.06x=148.50
.06x=27
x=450
1200-x=750
$1200 invested at 12%=$450
$1200 invested at 6%=$750
