4. The Men's W'arehouse determines that in order to sell q suits per week, the price per suit (in dollars) must be p = 150 0.5q. They also know that the total cost (in dollars) of producing q suits is C = 4-000 + 0.25q2. What is the maximum possible prot? Remember to justify that your answer is a maximum. 5. It is estimated that the cost of constructing an office building that is n floors high is C = 3n2 + 500n + 1810, where C is measured in thousands of dollars. How many floors should a building have in order to minimize the average cost per floor? (Hint: If the critical point is not an integer, check neighboring points.)
