According to Newton's Law of Cooling, if a body with temperature T, is placed in surroundings with temperature To different from that of T,, the body will either cool or warm to temperature T after t minutes, where T(!) = To + (T, -Tole -kt. A chilled jello salad with temperature 45.F is taken from a refrigerator and placed in a 68"F room. After 5 minutes, the temperature of the salad is 54"F. Use Newton's Law of Cooling to find the salad's temperature after 15 minutes. After 15 minutes the jello salad will have a temperature of F. (Round to the nearest integer.)
