Answer and Explanation:
The computation is shown below:
Current residual Income is
= current investment base × (Current ROI - Target ROI)
= $9,300,000 × (13% - 9%)
= $9,300,000 × 4%
= $372,000
Now
New residual income is
= (New investment base) × (New ROI - target ROI)
= ($9,300,000 + $5,700,000) × (12.24% - 9%)
= $15,000,000 × 3.24%
= $486,000
Yes, Monarch division should make the investment because the new residual income is more than the present residual income
