A sales team estimates that the number of new phones it will sell is a function of the price that it sets. It estimates that if it sets the price at x dollars, it will sell f(x)=6,228−9x phones. Therefore, the company's revenue is x⋅(6,228−9x). Find the price x that will maximize the company's revenue.
