Mila is deciding between two parking garages. Garage A charges an initial fee of $7 to park plus $4 per hour. Garage B charges an initial fee of $3 to park plus $5 per hour. Let A represent the amount Garage A would charge if Mila parks for t hours, and let B represent the amount Garage B would charge if Mila parks for t hours. Write an equation for each situation, in terms of t, and determine the interval of hours parked, t for which Garage A is cheaper than Garage B. A=
B=
