Question 429637: The revenue function in terms of the number of
units sold ,x, is given as
R = 270x-0.1x^2
where R is the total revenue in dollars. Find the number of units

R+=+270x-0.1x%5E2
The function reaches a maximum where the derivative is equal to 0.
dR%2Fdx+=+0+=+270+-+0.2x
Solving for x gives x = -270/-0.2 = 1350
So the number of units which produces the maximum revenue = 1350
Substituting this value in the original equation gives the revenue:
R+=+270%281350%29+-+0.1%281350%29%5E2
This gives R = $182,250
The function looks like this:
