15% of 30,000= 4500
Investment I 16.00% per annum ---x
Investment II 12.00% per annum ---y
x + y= 30000 ------------------------1
16.00% x + 12.00% y= = $4,500.00
Multiply by 100
16 x + 12 y= = $450,000.00 --------2
Multiply (1) by -16
we get
-16 x -16 y= = -480000.00
Add this to (2)
-4 y= = -30,000.00
divide by -4
y = $7,500.00 investment at 12.00%
Balance $22,500.00 investment at 16.00%
CHECK
$22,500.00 --------- 16.00% ------- $3,600.00
$7,500.00 ------- 12.00% ------- $900.00
Total -------------- $4,500.00
