A girl read a book that had 1,159 pages. She read 72 pages on the first day. She then read 40 pages per day until she finished the book. Which equation can be used to find the number of days, d, it took her to read the book?

A boy read a book that had 2,100 pages. He read 100 pages on the first day. He then read 85 pages per day until he finished the book. Which equation can be used to find the number of days, d, it took him to read the book?
