Blake is deciding between two parking garages. Garage A charges an initial fee of $10 to park plus $3 per hour. Garage B charges an initial fee of $3 to park plus $4 per
hour. Let A represent the amount Garage A would charge if Blake parks for t hours,
and let B represent the amount Garage B would charge if Blake parks for t hours.
Write an equation for each situation, in terms oft, and determine which garage
would be cheaper if Blake needs to park for 12 hours.
