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.

momto2 Posted September 8, 2012 Author Share Posted September 8, 2012 The answer was 70 I am not sure how to draw the model here, but Vivian had 5 units and Irene 1 unit When Vivian gave Irene 20 stickers, Vivian had 4 units and Irene had 2 units which is twice as many for Vivian than Irene. So one unit is 20 stickers. So in total now Vivian had 80 stickers So 80-10=70 Which is what Pam has Quote Link to comment Share on other sites More sharing options...
