suppose a competitive firm has the following cost:

Q 0 1 2 3 4 5 6 7 8 9

TC ($) 50 54 62 74 90 110 134 162 194 230

(Q: output ; TC: total cost)

1 Assume market price is $12 how much should the firm produce to maximize profit?

2 How much profit will it earn at $12?

3 Assume market price is $28, how much should the firm produce to maximize profit?

4 How much profit will it earn at $28?

5 From #1 #4 we can conclude: as price increases, firm produces (less, more) and profit (decreases, increases) circle the correct ones.
