After sitting on a shelf for a while, a can of soda at a room temperature ( 6 8 β 68 β F) is placed inside a refrigerator and slowly cools. The temperature of the refrigerator is 3 6 β 36 β F. Newton's Law of Cooling explains that the temperature of the can of soda will decrease proportionally to the difference between the temperature of the can of soda and the temperature of the refrigerator, as given by the formula below: T = T a + ( T 0 β T a ) e β k t T=T a β +(T 0 β βT a β )e βkt T a = T a β = the temperature surrounding the object T 0 = T 0 β = the initial temperature of the object t = t= the time in minutes T = T= the temperature of the object after t t minutes k = k= decay constant The can of soda reaches the temperature of 5 8 β 58 β F after 20 minutes. Using this information, find the value of k k, to the nearest thousandth. Use the resulting equation to determine the Fahrenheit temperature of the can of soda, to the nearest degree, after 95 minutes.
