The temperature change of the pie follows Newton's Law of Cooling, which states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature. Using the given information, we can set up the equation based on this law and solve for the temperature at 35 minutes. The correct answer, after applying the formula and calculations, is approximately 192.8ºF.
