A fast food resturant wants a container that can quickly cool coffee from 200 degrees to 130 degrees and keep the liquid between 110 and 130 degrees for as long as possible. Here are the choices:

a. CK company has a containter that reduces the temp of a liquid from 200 degrees to 100 degrees in 30 mins by maintaining a constant temp of 70.

b. Temp company has a container that reduces the temp of a liquid from 200 to 110 degrees in 25 mins by maintaining a constant temp of 60 degrees.

Use Newton's law of cooling to find a function relating the temp of the liquid over time for each container.
