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

### Instruction:
Lance wants to finish reading a 100 page book in 3 days. Yesterday, he started to read 35 pages. Today, he read 5 fewer pages than yesterday. How many pages should he read tomorrow to finish the book?

### Response:
Lance read 35 - 5 = <<35-5=30>>30 pages today.
So, he read a total of 35 + 30 = <<35+30=65>>65 pages in 2 days.
Therefore, he should read 100 - 65 = <<100-65=35>>35 pages tomorrow.
