Question 1183538
A company that manufactures flash drives knows that the number of drives x it can sell each week is related to the price p, in dollars, of each drive by the equation x=1200-100p
Find the price p that will bring in the maximum revenue. 
:
R = p * x
replace x with 1200-100p
R(p) = p(1200-100p)
R(p) = 1200p - 100p^2
or 
R(p) = -100p^2 + 1200p
using the vertex formula: p = -b/(2a) where a = -100, b = 1200
p = {{{(-1200)/(2(-100))}}}
p = $6 is the price that will give max revenue
