Answer:
The options are not well written, so i will answer in a general form.
We know that he has 6 days left to finish the reading.
We also know that he, at maximum, can read 22 pages per day.
Then in 6 days, the maximum number of pages that he can read is 22 times 6, or:
22*6 = 132 pages.
But this is the maximum, he could read any number between 0 and 132.
Then he could complete the reading project if he has P pages, left, where P is a number between:
0 ≤ P ≤ 132
This means that the book he selects must have at maximum, 132 pages.
that is the inequality we are looking for.
