Profit Parabolas: The baseball card shop is trying to sell limited baseball cards for $30, yet no one is interested in buying the cards. The owner of the baseball card shop, reduced the price of the cards to help sales. The baseball card owner found for every $1 that, the price was reduced, it created 8 more customers daily( per day). If the baseball card owner reduced the price to $ 20, how many people(customers) will be buying baseball cards each day? What will be the total profit? What should be the price of the baseball cards to create the greatest profit for the owner? Graph the function. Clearly label the graph.
