Answer:
Return on investment = 21%
Residual Income = $428,960
Explanation:
Average operating assets (AOA) = $3,064,000
Controllable margin (CM) = $643,440
Minimum rate of return (MRR) = 7 %
The return on investment is the ratio between the controllable margin (CM) and the average operating assets (AOA):
[tex]ROI = \frac{CM}{AOA} =\frac{643,440}{3,064,000} \\ROI = 0.21 =21\%[/tex]
The residual income is given by:
Residual Income = CM - (MRR × AOA)
[tex]RI=643,440 -(0.07*3,064,000)\\RI=\$428,960[/tex]
