A pilot takes a taxi from the airport to a hotel. The taxi driver charges a $2.50 initial charge plus $2.65 per mile. Which equation can be used to find y, the total cost of the trip, if x represents the number of miles of the trip?

y = 2.50x + 2.65
y = 2.65(x + 2.50)
y = 2.65x - 2.50
y = 2.65x + 2.50
