Revenue For groups of 80 or more people, a charter bus company determines the rate r (in dollars per person) according to the formula r = 15 − 0.05 ( n − 80 ) , n ≥ 80 where n is the number of people. (a) Express the revenue R for the bus company as a function of n. (b) Complete the table. n 100 125 150 175 200 225 250 R (c) Is the formula for the rate a good one for the company? Explain your reasoning.
