Answer:
a. Division's margin = Net operating income / Total sales
Division's margin = $4,069,146 / $32,948,550
Division's margin = 0.1235000
Division's margin = 12.35%
b. Division's turnover = Total sales / Average operating assets
Division's turnover = $32,948,550 / $9,027,000
Division's turnover = 3.65 times
c. Division's return on investment = Division margin * Division turnover
Division's return on investment = 12.35% * 3.65 times
Division's return on investment = 45.08%
