A woman is waiting for her coffee for 7 minutes before walking up to the pick- up counter and asking why it's taking so long. A barista reaches down and grabs a coffee and says, "I just finished up with it, here you go." The woman takes it to a table outside and reads for 4 minutes before taking a sip. It's cold. Maybe body temperature, she thinks. (You can use a rough estimate of body temperature.) Should she go back in and demand a new coffee because the barista lied, or does she only have herself to blame? Assume the room temperature is 68° F and it's 85° F outside. (Assume the same decay constant (usually called k) as in the previous problem.)
