An object with an initial temperature of To that is placed at time t = 0 inside a chamber that has a
constant temperature of T, will experience a temperature change according to the equation;
T = Ts + (To-Ts)e-kt
where T is the temperature (in F) of the object at time t (in hours), and k is a constant. A soda
can at a temperature of 120°F (after being left in the car) is placed inside a refrigerator where the
temperature is 38° F. Determine, rounded to two decimals, the temperature of the can after three
hours. Assume k = 0.45.
