Cost,Revenue,and Profit: Estimate the number of scanners that would produce a maximum profit when p is the price per scanner and x is the number of scanners. p= 100-0.0001x and the cost for producing x scanners is C= 350,000+30x and the profit for producing and selling x scanners is P=R-C=xp-C. SOmehow I got P=-0.0001x^2+70x-350000. Can you verify that? I tried graphing it to get the number of scanners for the maximum profit, but my calculator doesn't work. Is there another way to find the maximum number of scanners?
