Profit = revenue - cost.

x items are sold for xP=200x-0.01x^2.

The cost of producing x items is C=50x+20000.


To maximise the profit we differentiate this: 150-0.02x and equate to zero, so x=150/0.02=50*150=7500.

To solve without using calculus:






This expression has the greatest value when x=7500.
