Determine the following:

1. What is the behavior of the TC as Output increases? Answer the same

question in regard to the TFC. Why the difference?

2. What do the AFC, AVC and ATC curves do as regards increases in output? Is

there a difference in the AFC? Why?

3. What does the MC curve do with regard to Output? Why? What is the

relationship between the MC curve and ATC, AVC curves? Would this

be important information for the Producer?

(B) Calculate Output using the formula: Profit = (Price – ATC) x Q

Hint: construct a new table to find new output at the different levels of ATC values (in first table) and profit in table 2 when price is \$250.

(C) Calculate Output using the formula: Profit = (Price – ATC) x Q

Hint: construct a new table to find new output at the different levels of ATC values (in first table) when price is \$180. Also find new profit/loss values first.

(D) Calculate Output using the formula: Profit = (Price – ATC) x Q

Hint: construct a new table to find new output at the different levels of ATC values (in first table) when price is \$140. Also find new profit/loss values first.

(E) Use price schedule to determine Q‘s. (Repeat the process for prices \$350, \$450,, \$550, and \$650 before presenting all the output computed at different price levels in the table below.

(F) What does short-run cost model tell you about the behavior of the firm in regard

to MC and Price?
