Given the following average cost function: A C equals 0.5 Q squared minus 19.5 Q plus 180 plus 300 over Q Exercise 3. Part a. -0.5 points- Write down the equation for Total cost (TC) and Marginal Cost (MC). (enter just the numbers, if there are decimals, use one decimal only. Use the decimal point, not the comma) TC=0.5Q3 - 19.5Q2 + 180Q + 300 and MC= 1.5Q2 - 39Q + 180 Blank 1 0.5 Blank 2 19.5 Blank 3 180 Blank 4 300 Blank 5 1.5 Blank 6 39 Blank 7 180 Question 7 0.5 Points Exercise 3. Part b. -0.5 points- Calculate the values of average cost (AC), marginal cost (MC), and total cost (TC) when Q=4. (enter just the numbers with no decimal places). AC=Blank 1; TC=Blank 2; and MC=Blank 3 Blank 1 Add your answer Blank 2 Add your answer Blank 3 Add your answer Question 8 0.75 Points Exercise 3. Part c. -0.75 points- Interpret the results found in part b. That is the values for AC, TC, and MC Question 9 1.25 Points Exercise 3. Part d. -1.25 points- Describe here step by step (or show how you solve it) how you find the value for Q at which Total Cost is minimum. Show how you check that the value is minimum.
