A model for a company’s revenue from selling a software package is R(p)=-2.5p^2+700p, where p is the price in dollars of the software. What price will maximize revenue? Find the maximum revenue.

Respuesta :

Let y = -2.5p^2 + 700p
{Differentiate}
dy/dp = -5p + 700
When dy/dp = 0,
-5p + 700 = 0
-5p = -700
-p = -140
p = 140
