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

### Instruction:
 如果珍妮特每天读80页，贝琳达每天读30页，那么珍妮特在6周内多读了多少页？


### Response:
 首先计算6周是多少天：6周 * 7天/周 = <<6*7=42>>42天
然后计算珍妮特每天多读的页数，将贝琳达的页数从珍妮特的页数中减去：80页/天 - 30页/天 = <<80-30=50>>50页/天
然后将每天的差异乘以天数，得出阅读页数的总差异：50页/天 * 42天 = <<50*42=2100>>2100页
