momto2 Posted September 7, 2012 Share Posted September 7, 2012 This is a problem from book 4 Vivian has 5 times as many stickers as Irene. After giving 20 stickers to Irene, Vivian has twice as many as Irene, and 10 more than Pam. How many stickers does Pam have? Does anyone know how to solve this using the bar model.
