A travel company uses a quadratic function to model the profit, in dollars, that it expects to earn from selling tickets to a river cruise at d dollars per person. The expression - 8 + 1000-900 defines
this function.
Without graphing, find the price that would generate the maximum profit. Then, determine that
maximum profit.
