A company sells hockey pucks. Their profit is given by P=2.5x2+14x8 where P is the profit (in hundreds of dollars) and x is the number of pucks sold (in thousands). Determine the number of pucks that need to be sold to have a profit of $500 . Hint: P is in hundreds of dollars. Think about what value of P corresponds to a profit of $500 .
