Suppose that an equation is given p=2x2+280x1000 , where x represents the number of items sold at an auction and p is the profit made by the business that ran the auction. How many items sold would make this profit a maximum? Solve this by graphing the expression in your graphing utility and finding the maximum using 2ndCALC maximum. To obtain a good window tor the curve, set x [0,200] and y[0,10000]
