hey Mark, If you have a graphing calculator, you can input the equation that you have for the combined profit. You can then go to the table and see for what value of x the profit is the greatest. If you don't have a graphing calculator, then basically it's a guess and check.
P.S. If your equation for combined profit is correct, it wouldn't take long for you to figure it out in homeroom using the graphing calculator.
