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

### Instruction:
Berry wants to make sure he reads an average of 50 pages a day. This week he read 43 pages on Sunday, 65 pages on Monday, and 28 pages on Tuesday. He had a soccer game and fell asleep early on Wednesday so he read nothing. On Thursday he read 70 pages, and on Friday he read 56 pages. How many pages does he have to read on Saturday to reach his goal?

### Response:
 เขาต้องอ่านหนังสือ 350 หน้าต่อสัปดาห์เพราะ 7 x 50 = <<7*50=350>>350
เขาอ่านหนังสือไปแล้ว 262 หน้าเพราะ 43+65+28+70+56 = <<262=262>>262
เขาต้องอ่านหนังสืออีก 88 หน้าในวันเสาร์เพราะ 350-262 = <<350-262=88>>88
