Marques is deciding between two parking garages. Garage A charges an initial fee of $5 to park plus $3 per hour. Garage B charges an initial fee of $7 to park plus $2 per hour. Let AA represent the amount Garage A would charge if Marques parks for tt hours, and let BB represent the amount Garage B would charge if Marques parks for tt hours. Write an equation for each situation, in terms of t,t, and determine the interval of hours parked, t,t, for which Garage A is cheaper than Garage B.
