Answer:
See below.
Step-by-step explanation:
For part 1
Expected return can be computed by working out net profits from the production of drills.
Contribution per drill = Selling price - variable costs
Contribution = 40 - 24 = $16/ drill
Total contribution = 16 * 30,000 = $480,000
Profit = Contribution - Fixed costs
Profit = 480,000 - 200,000 = $280,000
Return on investment = Profit / Initial investment
ROI = 280,000 / 800,000 = 35%
Residual income = Net income - Equity charge
RI = 280,000 * (800,000*0.15) = $160,000
For part 2
We assume that this special order of 10,000 drills is in addition to the existing 30,000 drills bringing the total to 40,000 drills sold per year.
We first calculate the income effect of this isolated 10,000 additional drills.
Selling price = 30/drill
Variable cost / drill = 24
Contribution / new drill = 6
Total contribution from the order = 6*10,000 = $60,000
Total profit increment from this order = 60,000 - 30,000 = $30,000
This brings the total profit from 40,000 drills to
= 30,000+280,000 = $310,000
Total investment now has been increased by $150,000 bringing the total to 150,000 + 800,000 = $950,000
ROI has changed to = 310,000 / 950,000 = 32.63%
Residual income has changed to as,
RI = 310,000 - (950,000*0.15) = $167,500
Although the return on investment has fallen by around 2.37% the residual income has increased. Daniels may accept this order to ensure he has a good customer base and their total market share may actually improve thus this order might be strategically important for the future of the business.
Hope that helps.
