Chapter 4.8, Problem 13AYU

Cooling Time of a Pizza Apizza baked at ${\text{450}}^{\text{o}}\text{F}$ is removed from the oven at $5:00$ PM and placed in a room that is a constant ${\text{70}}^{\text{o}}\text{F}$. After $5$ minutes, the pizza is at ${\text{300}}^{\text{o}}\text{F}$.

At what time can you begin eating the pizza if you want its temperature to be ${\text{135}}^{\text{o}}\text{F}$?

Determine the time that needs to elapse before the temperature of the pizza is ${\text{160}}^{\text{o}}\text{F}$.

What do you notice about the temperature as time passes?
