Suppose that a firm is currently employing 30 workers, the only variable input, at a wage rate of $60. The average product of labor is 30, the last worker added 12 units to total output, and total fixed cost is: $3,600.

a. What is marginal cost?

b. What is average variable cost?

c. How much output is being produced?

d. What is average total cost?

e. Is average variable cost increasing, decreasing or constant? What about average total cost>

Do a little research and then take a shot. What do you think?
Hint. All of these questions need simple algebra.

Repost, and I or others will check your answers.

Here's my guess:

a. Marginal Cost
- change in TC/change in Q
so... 3600/12 = 300??

b. Average variable cost
- TVC/Q
so... i'm not sure how to find TVC, is it 20*60 = 1200, which would then mean 1200/600 = 2? But i'm not sure if 2 is too low for AVC?

c. Output = 20*30 = 600

d. ATC
- TC/Q
I'm not sure how to find total cost, but can I just use TFC and do 3,600/600 = 6? (then again that might be a little low for ATC :(

e. AVC would be increasing if each worker adds more output? and ATC would be inceasing as well?

Sigh, I hope my answers don't make me look stupid, I feel way over my head here, but thanks for the help in advance.
