Samantha wants to make scrapbooks with old family photos. An online
scrapbooking company charges $13 for a basic book and $4 per page.
Meanwhile, a family friend is willing to make a scrapbook for $49 plus $3
per page. For a certain number of pages, the price would be equal. How

13 + 4 p = 49 + 3p solve for p
p = 36
cost will be 13 + 4(36) = $________
