Daniel and Audrey are reading the same book. At the beginning of the month, Daniel was on page 49 and Audrey was on page 22. Daniel will read 17 pages per day and Audrey will read 20 pages per day. Let DD represent the page of the book that Daniel is on at the end of tt days into the month, and let AA represent the page of the book that Audrey is on at the end of tt days into the month. Write an equation for each situation, in terms of t, t, and determine what page Daniel and Audrey will be on on the day they are both on the same page.
