     Silver Scooter inc. finds that it costs $200 to produce each motorized scooter and that the fixed costs are $1, 500. The price is given by = - 500 - 2x, where p is the price in dollars at which exactly x scooters will be sold. Find the quantity of scooters that the company should produce and the price it should charge to maximize profit. Find the maximum profit.  How many scooters should the company produce to max-we profit?   
  
  Solution
Given
 
 $300 a scooter
 $1500 fixed cost
 p = 700 - 2x
 p is price
 x number of scooters sold
 
 The profit is revenue - production cost
 
 Pr = px - (200x + 1500)
 = x(500 - 2x) - (200x + 1500)
 = -2x^2 + 300x - 1500
 
 Taking the derivative
 
 Pr\' = -4x + 300
 
 Setting it to zero
 
 -4x + 300 = 0
 x = 75
 
 The quantity of scooters should be 75
 
 The price should be
 
 p = 500 - 2*75
 = $350
 
 The maximum profit will be
 
 Pr = -2(75)^2 + 300(75) - 1500
 =$9750
