Explanation:

A.Calculation for  each division’s ROI

Using this formula

Return on Investment

=Net Income/Average Invested Assets

Let plug in the formula  

Residential$68,000.00/$200,000.00=34.00%

Professional$153,300.00/$365,000.00=42.00%

B.Calculation for  each division’s sales margin. Interpret your results

Using this formula

Sales Margin= Operating income/Sales

Let plug in the formula

Residential$68,000.00/$850,000.00=8.00%

Professional  $153,300.00/$1,095,000.00=14.00%

C.Calculation for each division’s capital turnover

Using this formula

Capital Turnover=Sales/Average operating assets

Let plug in the formula

Residential$850,000.00/$200,000.00=4.25

Professional$1,095,000.00/$365,000.00=3.00

D.Using  the expanded ROI formula to confirm the results from Requirement a.

Using this formula

Return on Investment=Profit Margin*Investment Turnover

Let plug in the formula  

Residential8.00%*4.25%  34.0%

Professional14.00%*3.00%  42.0%

E.Calculation for  each division’s residual income (RI)
