• $0.30 per minute • $1.35 base fee • $2.80 service fee • $0.79 per mile Suppose you sometimes use this service for your 7-mile trip to work in the morning. Let P = m(L) represent the price of the ride, where L is the length of time the ride takes (in minutes). Calculate the price for a trip taking 14 minutes. Answer: 13.88 dollars What is the formula for the function P = m(L)? Answer: m(L) = 9.68 + .30L From your experience, you know that if you leave at your usual time (6:00 A.M.) the ride takes about 12 minutes. The ride time increases when you leave later in the morning, taking about 16 minutes if you leave at 10:00 A.M. Let L = n(T) represent the length of time (in minutes) the trip takes you, where the input T is the number of hours after 6:00 A.M. Which expression represents the length of time the trip takes if you leave at 7:00 A.M.? O m(1) O m(7) O n(7) O n(1) Use function notation (with m and n) to write a composition representing the price of a ride to work if you leave at 7:30 A.M. Answer: dollars
