Answer:
max of 7 hours
Explanation:
First, calculate the maximum amount they can spend on parking:
total budget - movie cost = parking budget
48 - 27 = 21
Therefore, they have a maximum of $21 to spend on parking.
We are told that parking costs $3 per hour. To calculate the number of hours they can park:
Parking budget ÷ cost of parking per hour = number of hrs parking
21 ÷ 3 = 7
Therefore, have enough money to purchase 7 hours of parking (in addition to spending $27 on the movie)
So they can spend a maximum of 7 hours in Kingsville
