Answer 1

In this situation the revenue is the total sales you make before all expenses.
To find the profit: 3000 - 1500 - 500 = 1000.
Your profit is $1,000.

Answer 2

The cost of goods was 1,500 and was sold for 3,000 and the selling expenses was 500 
The profit is 3,000-1500-500=1000
therefore the profit is 3,000
