How do I find P? This is business calc

The price-demand equation and the cost function for the production of table saws are given, respectively, by x = 9082 - 50p C(x) = 68x + 46705.12 where a is the number of saws that can be sold at a price of $p per saw and C(x) is the total cost (in dollars) of producing x saws. A. Find P'(2162). P'(2162) = 299221 X ' 27.16 (Round your answer to two decimal places as needed.) B. Interpret these results. At a production level of 2162 table saws, profit is increasing at the rate of $ 29922( X 27.16 per saw
