Sydney is deciding between two parking garages. Garage A charges an initial fee of
$12 to park plus $4 per hour. Garage B charges an initial fee of $7 to park plus $5 per
hour. Let A represent the amount Garage A would charge if Sydney parks for t hours,
and let B represent the amount Garage B would charge if Sydney parks for t hours.
Write an equation for each situation, in terms of t, and determine the hours parked,
t, that would make the cost of each garage the same.
