Solve the problem.Newton's Law of Cooling states that the temperature of a heated object decreases exponentially over time toward the temperature of the surrounding medium. Suppose that a coffee is served at a temperature of 132°F and placed in a room whose temperature is 70°F. The temperature ? (in °F) of the coffee at time t (in minutes) can be modeled by ?(t) = 70 + 62e-0.08t. What is the temperature of the coffee in 5 minutes?
A. 116.6°F B. 111.6°F C. 115.0°F D. 108.4°F
