Q

Difference between pure and perfect competition

What is profit ?
What is total revenue?
What is AR?
What is MR?

A

-Profit is the difference between total revenue received on sales of a given output and total cost of production.

-AR Is PQ/Q which is P
-MR is the revenue derived from the sale of an additional unit of output
