Answer :
The dollar amount for the return on stocks is $3375 and the dollar amount for the return on bonds is $1125.
Two equations can be derived from the question:
s + b = $90,000 equation 1
0.1s + 0.02b = $4500 equation two
$4500 = 0.05 x $90,000
The above equation is a simultaneous equation and it would be solved using the elimination method.
The following steps would be take to determine the value of b
Multiply equation 1 by 0.1
0.1s + 0.1b = 9000 equation 3
Subtract equation 2 from 3
0.08b = $4500
b = $56,250
The following step would be taken to determine the value of s
Substitute for b in equation 1
s + $56,250 = $90,000
$90,000 - $56,250 = s
s = $33,750
Dollar amount for the return on stocks = $33,750 x 0.1 = $3375
Dollar amount for the return on bonds = $56,250 x 0,02 = $1125
