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

### Instruction:
 詹姆斯买了3件衬衫，总共花了60美元。有40%的折扣。打折后，他每件衬衫付了多少钱？


### Response:
 60美元的40%是0.4 * 60 = <<0.4*60=24>>24美元。
因此，折扣后的价格是60 - 24 = <<60-24=36>>36美元。
每件衬衫的价格是36/3 = <<36/3=12>>12美元。
