A large room has a temperature of 70 degrees Fahrenheit. When a cup of tea is brought into the room, the tea has a temperature of 120 degrees Fahrenheit. The function f(t) = C * e^(kt) represents the situation, where t is time in minutes, C is a constant, and k is a constant.
After 3 minutes, the cup of tea has a temperature of 100 degrees Fahrenheit. What will be the temperature of the tea, in degrees Fahrenheit, after 5 minutes? Round your answer to the nearest tenth and do not include units.
