The output and cost of production of rice (in bags) are presented in the table below. Use the information in the table to answer the questions that follow: 
                        
                        
                      
                        
                          | Output of rice    (in bags |   0 |   1 |   2 |   3 |   4 | 
                        
                          | Total    Variable         Cost(TVC) $
 |   0 |   5 |   7 |   10 |   20 | 
                        
                          |   Total Cost(TC)    $ |   7 |   12 |   14 |   17 |   27 | 
                        
                      
                        
                       Calculate the
                        
                      Average Fixed Cost (AFC) at output levels 0, 2 and 4.
                        Marginal Cost (MC) at all levels of output.
                       If the price of a bag of rice were $ 10,
                      calculate the profit/loss at all levels of output.
                        at what output level(s) is the maximum profit made?
                       Draw the marginal cost curve (the use of graph is essential).
