Matlab Question ( Temperature Calculation )

QUESTION 1

An object with an initial temperature of To that is placed at time t=0 inside a chamber that has a constant temperature of Ts, will experience a temperature change according to the equation:

T = Ts + (To - Ts) e ^-kt

where T is the temperature of the object at time t (in hour), and k is a constant.  A soda can at a temperature of 120⁰ F (was left n the car) is placed inside a refrigerator where the temperature is 38⁰ F.  Determine the temperature of the can after three hours.  Assume k=0.45.  First, define all the variables and then calculate the temperature using one MATLAB command.
