Below is an instruction that describes a task. Write a response that appropriately completes the request in Chinese. Please answer in Chinese.

### Instruction:
 Rachel weighs 75 pounds, 6 pounds less than Jimmy and 15 pounds more than Adam. What is the average weight of the three people, in pounds?


### Response:
 首先通过将6磅加到Rachel的体重上找到Jimmy的体重：75磅+6磅 = <<75+6=81>>81磅
然后通过从Rachel的体重中减去15磅找到Adam的体重：75磅-15磅 = <<75-15=60>>60磅
然后将三个体重相加以找到总体重：81磅+60磅+75磅 = <<81+60+75=216>>216磅
然后将总体重除以人数以找到每个人的平均体重：216磅/3人 = <<216/3=72>>72磅/人
