question
If a Firm's Total Costs (TC) can be given by the following equation:
TC = 8,000 + 50Q + 10Q2
What is the Firm's Average Total cost function
TC = 8,000 + 50Q + 10Q2
What is the Firm's Average Total cost function
answer
ATC = 8000/Q + 50 + 10Q
question
If a Firm's Total Costs (TC) can be given by the following equation:
TC = 8,000 + 50Q + 10Q2
What is the Firm's Marginal cost (MC) function?
TC = 8,000 + 50Q + 10Q2
What is the Firm's Marginal cost (MC) function?
answer
MC = 50 + 20Q

question
If you are told that for a typical firm in a Perfectly Competitive Market the Market Price is $50, they sell 100 units a day, and the $ value of their Minimum Average Total Cost is $40 then which of the following statements is correct?
