Tanya took a cab from her home to the airport. Her total fare including a tip of $5.00, was $28.50. EZ Cab Company has a pick-up
-at-home charge of $2.50, which is not shown on the meter. The cab meter charges $1.00 for the first 0.2 mile and $0.25 for each additional 0.2 mile traveled. With this information, my question is: How much did the cab meter show when Tanya arrived at the airport?
