I am a student and I am doing accounting as one of my modules.

It depends on the information provided in the problem. Revenues are what you receive or have title to for providing goods and services. For example you provided accounting service to a customer for a set fee. The fee you charged for providing the service to the customer is revenue to you. Also if you sold an item to a customer for a set price, then the price charged for the sale of the item is revenue to you.

Hi I think that I can help, but there are many ways to calculate the revenue it depends on the type of the problem you asked the question in a very general way. We have to know what info are provided in the problem to help you.
