Benjamin used regression analysis to fit quadratic relations to monthly revenue, R, and total cost, TC, data with the following results, where Q is quantity.
R = ?0.008Q2 + 32Q TC = 0.005Q2 + 2.2Q + 10 (a) Using a spreadsheet, plot R and TC. Estimate the quantities QBE and Qp, where the maximum profit should occur. Estimate the amount of profit at this quantity. (b) The profit relation P = R ? TC and calculus can be used to determine the quantity Qp at which the maximum profit will occur and the amount of this profit. The equations are: Profit = aQ2 + bQ + c Qp = ?b/2a Maximum profit = ?b2/4a + c Use these relations to confirm your graphical estimate of QP. (Your instructor may ask you to derive the relations above.)
