    P=-0.0002x^2+140x-250000 here we can see it's an upside down/inverted parabola indicated by the -0.0002x^2 for the maximum profit it will be at the maximum point, so just graph and find the max or work out the max by hand. of course you are looking for your y value which is known as P(profit) in this context and your x is just how many units you sold.

    That parabola does not represent the equation given, I just wanted to show you the concept of it for a better understanding.

    the problem is that you window is probably to small, you will have to adjust the x and y values in that graphing part somewhere, I do not use your calculator so unfortunately I cannot help you find it.
