Answer the following:
1. The fee to park in the parking lot of a shopping mall costs P50.00 for the first
three hours and an extra P15.00 for each hour (or a fraction of it) after that. If you
park for more than six hours, you instead pay a flat rate of P150.00. Represent
your parking fee using the function p(t) where t is the number of hours you parked
in the mall.
