A waiter brings a hot bowl of soup to you in a restaurant and says “enjoy it while it’s warm.” The temperature of the bowl of soup, in degrees Fahrenheit, is F(m)= 76 + 54e ^-0.162m, where m is the time, measured in minutes, since it was brought to the table. The graph of this model is shown below in a picture.
Questions below.
Not required to answer every question.

Q1: What was the temperature of the soup when it was first brought to you?

Q2: What is the room temperature?

Q3: What is the temperature of the soup after 7 minutes?

Q4: If the perfect temperature of the soup is 85 degrees Fahrenheit, how many minutes does this model predict it will take to cool down to the perfect temperature?
