<PRE><B>Question 1040512</B>
the profit P, in dollars, is given by
P(x) = –0.002 x2 + 4.1x – 1600 
(a) What is the company’s profit if 700 donuts are made daily? 
answer:: P(700) = -0.002*700^2 + 4.1*700 - 1600 = $290.00
----------------------------------------------- 
(b) How many donuts should be made daily in order to maximize the company’s profit?
Max occurs when x = -b/(2a) = -4.1/(2*-0.002) = -4.1/-0.002 = 4100/2 = 2050 
------
Cheers,
