According to Newton's Law of Cooling, if a body with temperature T, is placed in surroundings with temperature To different from that of T₁, the body will either cool or warm to temperature T after t minutes, where T(t) = T₁+(T₁-Toekt. A chilled jello salad with temperature 42°F is taken from a refrigerator and placed a 68°F room. After 10 minutes, the temperature of the salad is 49°F. Use Newton's Law of Cooling to find the salad's temperature after 20 minutes. After 20 minutes the jello salad will have a temperature of (Round to the nearest integer.) °F.
