A publisher needs to send many books to a local book retailer and will send the books in a combination of small and large boxes. Each small box can hold 25 books and each large box can hold 50 books. A total of 5 boxes were sent which can hold 200 books altogether. Graphically solve a system of equations in order to determine the number of small boxes sent, x, x, and the number of large boxes sent, yy.
