A company has 1000 widgets and will bbe able to sell all of them if the price is one dollar. The company will sell one less widget for each 10-cent increase in the price it charges. What price will maximize revenues, where revenue is the selling price times the quantity sold? _________________ I know that I have to make a system of equations, and then multiply the equations I get for price and quantity together, all under one variable. I take the derivative of that equation and find the maximum value... However, I do not know how to start my equations which is, unfortunately, the hard part.
