A manufacturer determines that the number of drills it can sell is given by this formula,
D = -2p2 + 140p - 200, where p is the price of the drills in dollars.

A. At what price will the manufacturer sell the maximum number of drills?

B. What is the maximum number of drills that can be sold?

(hint: graph the equation, and use some of the calculate features to determne maximum values.)
Answer

B. 2250 drills
b. A. $30

B. 2415 drills
c. A. $20

B. 200 dirlls
d. A. $50

Well you can solve the equation D=0 and find p for the first question. And for the second one you can maximize the function either by using the graph if you know how to draw it or the equation.
