1. Given the following total-cost schedule:

___Q________0_____1_____2_____3_____4_____
TC 1 12 14 15 20

( a) Derive the average- and marginal-cost schedules.
(b) Derive the total-revenue, average-revenue, and marginal-revenue schedules from Q = 0 to Q = 4 by 1s.

Average revenue (AR) = total revenue (TR) / Q

Marginal revenue (MR) = change in total revenue / change in Q

For example Q TR AR MR
2 14 7
3 18 6 4
