QUESTION 1 0.1 p Cost function is C(q) = 25 + 3q. What is marginal cost at q = 5? QUESTION 2 0.1 Cost function is C(q) = 20q. What is marginal cost at q = 10? QUESTION 3 If the production of an additional unit raises total cost by more than the previous unit, the marginal cost of that unit must be increasing. O True O False QUESTION 4 Average total cost is ATC(q) = 100 - + q. What is marginal cost at q = 25? (Hint: First multiply by q to obtain total cost.)
