<PRE><B>Question 824418</B>
The manufacturer of a CD player has found that the revenue R (in dollars) is
R(p)=-5p(squared)+1330p when the unit price is p dollars. If the manufacturer sets the price p to maximize revenue, what is the maximum revenue to the nearest whole dollar?
-------
To find maximum R(p)
1. Find the vertex of R(p)
OR
2. Find and solve the derivative of R(p) ; if you know calculus.
-------
Find the vertex::
Max occurs when p = -b/(2a) = -1330/(2(-5)) = 133
---
Max Revenue = R(133) = $88445
---------------
