Question 1120310
<br>
(a) The maximum value of the expression ax^2+bx+c (where a is negative) is at x = -b/2a.  For the expression in this problem, x = -4/(2(-2)) = 1.<br>
Since the units are thousands, the maximum profit will be when the number of units produced per week is 1,000.<br>
(b) The maximum profit, in hundreds of dollars, is the value of the expression when x = 1: -2+4+3 = 5 (hundred dollars)<br>
Not much of a business.... produce 1000 items in a week to make a profit of $500....
