A chilled jello salad with temperature 40F is taken from a refrigerator and placed in a 68F room. After 15 minutes, the temperature of the salad is 46F. Use Newton's Law of Cooling to find the salad's temperature after 20 minutes.

So, Newton's Law says that
T(t) = 68 + (40-68)e^(-kt)
Since T(15) = 46, k = 0.016
Now just find T(20)
T(t) = 68 + (40-68)e^(-kt)
Since T(15) = 46, k = 0.016
Now just find T(20)
