Answer:
a. Minimum acceptable income from operations as of 10% of invested assets
Retail Division = $690,000 * 10% = $69,000
Commercial Division = $770,000 * 10% = $77,000
Internet Division = $430,000 * 10% = $43,000
Residual Income = Income from Operation - Minimum acceptable income from operations as of 10 percent of invested assets
Retail Division Residual Income = $138,000 - $69,000
= $69,000
Commercial Division Residual Income = $138,600 - $77,000
= $61,600
Internet Division Residual Income = $64,500 - $43,000
= $21,500
b. Retail Division has the most Residual Income with the amount of $69,000
