Newton's Law of Cooling states that the rate at which an object cools is proportional to the difference in temperature between the object and the surrounding medium. Thus, if an object is taken from an oven at $294^{\circ}$F and left to cool in a room at $72^{\circ}$F, its temperature $T$ after $t$ hours will satisfy the differential equation $$\dfrac{dT}{dt} = k (T - 72).$$ If the temperature fell to $202^{\circ}$F in 0.8 hour(s), what will it be after 5 hour(s)? After 5 hour(s), the temperature will be degrees F.
Hint: Newton's Law of Cooling is discussed in the book on pages 240--241.
