A company sells widgets. The amount of profit y made by the company is related to the selling price of each widgets x by the giv
SCORPION-xisa [38]

Answer:

The maximum amount of profit is 32

Step-by-step explanation:

Given

y=-x^2+64x-292

Required

Determine the maximum profit

This is calculated by calculating the maximum of the function.

A quadratic function is of the form

y = ax^2 + bx + c

and its maximum is:

Max = \frac{-b}{2a}

So: y=-x^2+64x-292

We have that

a = -1

b = 64

c = -292

Max = \frac{-b}{2a}

Max = \frac{-64}{2 * -1}

Max = \frac{-64}{-2}

Max = 32

<em>Hence, the maximum amount of profit is 32</em>
