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)
