A parking garage allows a visitor to park for free if they stay less than 2 hours. If they stay more than 2 hours but less than 5 hours, they will be charged Php30. Php50 if they stay more than 5 hours but less than 7 hours and an additional Php15 per hour for staying more than 7 hours (or a fraction of it).

Compute the amount of parking fee if a visitor stays for a. 1 hour and 30 minutes b. 4 hours c. 6.75 hours d. 10 hours and 15 minutes
