An ice cream company varies the prices of its pint containers to maximize profit. The function F(x)=-80(x-3)2+150 models the company’s profits in thousands of dollars, where x is the price of a pint of ice cream in dollars. At what price will the company receive maximum profits? How much profit will the company earn?
The Maximum profits the company can earn is 150
