Answer: D & C
Explanation:
The net Income of the business is represented as
Net profits or income = Net sales revenue (gross income) – Cost of goods and services sold – Administration, operating, marketing, and advertising costs, taxes, interests, and other expenses.
Here C is an option because we need to take operating expenses into consideration but if you consider cost of goods brought into store as operating then option changes to D.
D represents the sales which helps us determine the net income of the business.
