<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?
<bot>: How much does Jake weigh? ** Jake weighs 8kg more than 52 kg which is 8+52 = <<8+52=60>>60 kg
How much do Tracy and Jake weigh together? ** Tracy and Jake together weigh 60+52 = <<60+52=112>>112kg
How much does John weigh? ** John therefore weighs 158-112 = <<158-112=46>>46 kg
What is the range of their weights? ** The range of their weights is 60-46 = <<60-46=14>>14kg
