Q:

At a canning company the daily production cost, y, is given by the quadratic equation y = 650 – 15x + 0.45x2, where x is the number of canned items. What is the MINIMUM daily production cost? A) $1,025.00 B) $1,186.25 C) $525.00 D) $536.25

Accepted Solution

A:
The equation is a parabola so the minimum point is the vertex.

(-b/2a, y)

x = 15/0.9 = 16.67 canned itemz
y = 524.95 $

So it's C.
