The number of pies available for sale at the Pie in the Sky Bakery varies over the
course of the day, and is given by P(t) = 30 - 212 +161, where t is the number of hours
since the store opens in the morning. What is the average rate at which this
number changes during the first t hours that the store is open?

How does a negative number relate to pies for sale? Typo?
It was probably p(t)=30-2t^2+16t
