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

### Instruction:
 伊利奥特的书有381页。他已经读了149页。如果他每天读20页，一周后还剩下多少页要读？


### Response:
 一周里，伊利奥特读了7 x 20 = <<7*20=140>>140页。
加上之前的阅读量，他总共读了149 + 140 = <<149+140=289>>289页。
还剩下381 - 289 = <<381-289=92>>92页要读。
