Hi, can someone please help me with the following questions?

Each unit of input, X, costs $10.  Fixed costs are $50, regardless of the level of output.

 a.                   Complete the table below.

 

Labor, X	Total Output (TPP)	Marginal Physical Product (MPP)	TFC	TVC	TC	AFC	AVC	ATC	MC/unit
0	0
1	15
2	45
3	70
4	90
5	105
6	110
7	112

 b.                  If the product can be sold for $0.75 per unit, what is the optimal level of output?

  

c.                   Find the level of profit at the optimal level of output.  Explain what would happen if the firm produced one more unit of output in terms of marginal cost and marginal revenue.


Please provide explanations for b and c.  Appreciate all the help I can get.  It's a school assignment. Thanks.

Sorry, this is the full table:

 and the two related questions:

b.                   If the product can be sold for $0.75 per unit, what is the optimal level of output?

Appreciate all the help I can get, along with the explanations for b and c.  Thanks!
