Question 5 Suppose your demand function is given by D(q) = -q - 2q + 517, where q is thousands of units sold and D(q) is dollars per unit. Compute the following, showing all calculations clearly. A) If 18000 units are to be sold, what price should be charged for the item? Price = $ B) If a price of $229 is set for this item, how many units can you expect to sell? (Give your answer as whole units, not in thousands of units.) You can sell whole units (Your answer should not be terms of thousands of units). C) At what value of q does D(q) cross the q axis? (When you give your answer, round your answer to three decimal places) It crosses at q = thousand units
