###Human: Tracy, John and Jake found their combined weight to be 158 kilograms. If Tracy weighs 52 kg and Jake weighs 8kg more than Tracy, what is the range of their weights?, ### Assistant: Jake weighs 8kg more than 52 kg which is 8+52 = 60 kg
Tracy and Jake together weigh 60+52 = 112kg
John therefore weighs 158-112 = 46 kg
The range of their weights is 60-46 = 14kg 
 So the answer is :  14
