Problem

Given the following total-revenue function:
	TR=9Q-Q(2)
A)	Derive the total, average, and marginal revenue schedules from Q=0  to  Q=6 by 1’s
B)	On the same set of axes, plot the total , average, and marginal-revenue schedules of part (a)
c) Then draw on the same set of axes the marginal-revenue curve derived in part 1 and the marginal-cost curve derived in problem 7, and use them to explain why the best level of output of the firm is 3 units.
d) Explain why your answer to part (a) is an example of marginal analysis and optimizing behavior in general.

Problem 7
Given the following total-cost schedule:
Q  	0	1	2	3	4
TC	1	12	14	15	20
Derive the average and marginal-cost schedule
