A solid object is dropped into a pond with a temperature of 20 degrees Celsius. The function f(t)=Ce(−kt)+20 represents the situation, where t is time in minutes, C is a constant, and k=0.0399. After 4 minutes the object has a temperature of 35 degrees Celsius. What was the initial temperature of the object?
