please answer all questions

pure competition in the short run and in the long run)

1.What is the condition for profit maximization for a pure competitive firm?

2.Graph the demand curve for a pure competitive firm, label the graph. What is the relationship between marginal revenue (MR) and the demand curve (is MR greater, equal, or less than the demand curve)?

3.What is relationship between total revenue (TR) and total variable cost (VC) if the price is less than AVC (is TR greater, less, or equal to VC)?

4.What is relationship between total revenue (TR) and total variable cost (VC) if the price is equal to the AVC (tangent to the minimum AVC), (is TR greater, less, or equal to VC)? What do we call this point?

5.What is relationship between total revenue (TR) and total variable cost (VC) if the price is between AVC and ATC (does TR covers part of VC, All VC or all VC and part of foxed cost)?

6.What is relationship between total revenue (TR) and total cost (TC) if the price is equal (tangent to the minimum) to ATC (is TR greater, less, or equal to TC)?What do we call this point?

7.What is relationship between total revenue (TR) and cost (TC) if the price is greater than ATC (is TR greater, less, or equal to TC)? Does the firm make positive economic profit or loss?

8.What portion of the marginal cost (MC) is the supply curve for a perfect competitive firm (the portion of MC that is above AVC, the portion of MC that is above ATC, all MC) choose one.
