A company sells widgets. The amount of profit, y, made by the company, is

denis23 [38]

Answer:

449.25 units

Step-by-step explanation:

The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation as follows :

$y=-x^2+51x-201$ ...(1)

For maximum profit,

Put dy/dx = 0So,

$\dfrac{d}{dx}(-x^2+51x-201)=0\\\\-2x+51=0\\\\x=\dfrac{51}{2}\\\\x=25.5$

Now put x = 25.5 in equation (1).

$y=-(25.5)^2+51(25.5)-201\\\\y=\$ 449.25$

so, the required answer is 449.25 units.
