Answer
Total number of pages in the book = 500
Pages read every day = 20
Pages read after 15 days = 20 × 15 = 300
Pages left after 15 days = 500 - 300 = 200
In general, after n days, the number of pages left will be:
Number of pages left = 500 - 20n
Hence, after 15 days, 200 pages will be left, and the linear pattern representing the number of pages left is (500 - 20n), where n is the number of days.
