To determine whether a company’s profits will justify purchasing its stock, an investor wants to know the maximum possible profits for the company's signature product. The profit formula for the signature product can be represented using the function P⁡(x)=−7⁢x^2+4,200⁢x−20,000 , where x is the selling price of the product. What numbers for the selling price and the projected profit at the maximum of the function can the investor use to determine whether purchasing the stock is viable? Round to the nearest cent if necessary. Enter your answer in the boxes.
