1. The problem asks: How much more glitter was used in the paper chain that used the most glitter than in the paper chain that used the least glitter? 2. From the graph description, the least glitter used is at 2 1/2 containers. 3. The most glitter used is at 3 1/2 containers. 4. To find how much more glitter was used, subtract the least amount from the most amount: $$3 \frac{1}{2} - 2 \frac{1}{2}$$ 5. Convert the mixed numbers to improper fractions: $$3 \frac{1}{2} = \frac{7}{2}$$ $$2 \frac{1}{2} = \frac{5}{2}$$ 6. Subtract the fractions: $$\frac{7}{2} - \frac{5}{2} = \frac{7 - 5}{2} = \frac{2}{2} = 1$$ 7. So, the paper chain that used the most glitter used 1 container more glitter than the one that used the least. Final answer: 1 container
