Task Analysis

To answer the given questions, we need to calculate the following: a) The number of pages left to read. b) The difference between the number of pages left to read and the number of pages already read. c) The number of days it will take to read the remaining part of the book if reading 6 pages per day.

Answer

a) To calculate the number of pages left to read, we need to subtract the number of pages already read from the total number of pages in the book. The book has 130 pages, and Igor read 5 days * 8 pages per day + 4 days * 9 pages per day = 40 + 36 = 76 pages. Therefore, the number of pages left to read is 130 - 76 = 54 pages.

b) To calculate the difference between the number of pages left to read and the number of pages already read, we subtract the number of pages already read from the number of pages in the book. The book has 130 pages, and Igor read 76 pages. Therefore, the difference is 130 - 76 = 54 pages.

c) To calculate the number of days it will take to read the remaining part of the book if reading 6 pages per day, we divide the number of pages left to read by the number of pages read per day. The number of pages left to read is 54 pages, and Igor reads 6 pages per day. Therefore, it will take 54 / 6 = 9 days to read the remaining part of the book.
