Final answer:
Employees of the Royal Motor Company are required to recognize as gross income 18% of the cost of the automobile purchased.
Step-by-step explanation:
The correct statement is option c) Employees of Royal are required to recognize as gross income 18% (20% - 2%) of the cost of the automobile purchased. Nonmanagement employees can buy a new automobile for Royal's cost plus 2%, while dealers can buy it at cost plus 20%. This means that nonmanagement employees receive a discount of 2% from the cost price, while dealers receive a markup of 20% from the cost price. Therefore, employees of Royal need to recognize 18% (20% - 2%) of the difference between the cost price and the actual price paid as gross income.
