You can put this solution on YOUR website! Fund A 6.30% per annum ---x
Fund B 8.80% per annum ---y
x+y=191610 ------------------------1
6.30%x+ 8.80%y= =$16,681.66
Multiply by100
6.3x+8.8y=$1,668,166.00 --------2
Multiply (1) by -6.3
we get
-6.3x-6.3y=-1207143.00
Add this to (2)
0x+2.5y=$461,023.00
divide by2.5
y = $184,409.20 investment at 8.80%
Balance $7,200.80 investment at 6.30%
CHECK
$7,200.80 --------- 6.30% ------- $453.65
$184,409.20 ------- 8.80% ------- $16,228.01
Total -------------- $16,681.66
