A freezer has a temperature of 14 degrees Fahrenheit. An ice-cube tray full of water is placed in the freezer. The function f(t) = Ce(-ki) + 14 represents the situation, where t is time in minutes, C is a constant, and k = 0.045. After 15 minutes the water has a temperature of 40 degrees. What was the initial temperature of the water? Round your answer to the nearest degree, and do not include units
