You are in charge of the marketing department. Your total operating budget last year was $20 million. Sales are expected to increase 17% this year. How would you approach budgeting this year using the zero-based budget approach? How would you approach budgeting from an incremental approach? Which is better? Why?

Can you please include the numbers in the answer to this question? I don't know what to do with the numbers and how to use it in the incremental budget approach.
