Looking fir this problem thank you

"Benefits" from operating a business are the revenues that are generated from sales. The monthly total revenue function for a company can be defined as; TR = Price (P) x Quantity Demanded (Q). If the monthly ordinary demand function for your firm is @ = 800 - 2P: a. What is the total revenue function for this firm in terms of @ (TR needs to be a function of @, not P)? b. What is the average revenue function for this firm in terms of Q? c. What is the MR function for this firm in terms of @? d. Show that MR will be less than AR for any positive level of Q. Why is that? Give an interpretation for this result. e. What is the quantity level that maximizes total revenue? What is the price that must be charged to maximize total revenue
