Quantity TVC
0 0
1 45
2 85
3 120
4 150
5 170

1)Compute ATC and MC
2) What is quantity if P=40
3)what is quantity if P=30
4)What is profit if P=35
5)What is relationship between marginal costs and the firms supply curve?

Take a shot. What do you think.

Hints: The change in TVC is MC. The firm will maximize when P=MC
