Question 551788
Recall that the vertex of a parabola *[tex \LARGE f(x) = ax^2 + bx + c] occurs at *[tex \LARGE x = -b/2a]. In this case the vertex is at *[tex \LARGE x = \frac{-50}{2(-.01)} = 2500]. Hence, 2,500 bracelets will maximize the profit. To find profit, simply find P(2500). You should get 32500 as your result.
