The liquid base of an ice cream has an initial temperature of 85°C before it is placed in a freezer with a constant temperature of -20°C. After 1 hour, the temperature of the ice-cream base has decreased to 55°C. Use Newton's law of cooling to formulate and solve the initial-value problem to determine the temperature of the ice cream 2 hours after it was placed in the freezer. Round your answer to two decimal places. T(2) =
