A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit. y = -5x² + 194x - 990

19.4

Step-by-step explanation:

Given

Profit is given in terms of the selling price

to get the maximum price, differentiate y w.r.t x

Put   to get maximum value

Thus, the company must sell it at 19.4

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
