Question 1109814: A company producing CDs for home computers finds that the total daily revenue for selling x items at p dollars per item is given by R(x) = 9x − 0.01x^2. Use the fact that R = xp and your knowledge of factoring to find a formula that gives the price p in terms of x.
p = ?

Use the formula to find the price they should charge if they want to sell 420 items per day.

R%28x%29+=+9x+-+0.01x%5E2
if R+=+xp , we have
xp+=+9x+-+0.01x%5E2
p+=+9x%2Fx+-+0.01x%5E2%2Fx
p+=+9+-+0.01x
the price they should charge if they want to sell 420 items per day will be:
p+=+9+-+0.01%2A420
p+=+9-+4.2
p+=++4.8
