1. The problem asks: How much more pink wax was used in the candle jar with the most pink wax than in the candle jar with the least pink wax? 2. From the line plot data, the candle jar with the most pink wax has 1 1/2 cups, and the jar with the least pink wax has 1 1/4 cups. 3. To find how much more wax was used, subtract the least amount from the most amount: $$1 \frac{1}{2} - 1 \frac{1}{4}$$ 4. Convert the mixed numbers to improper fractions: $$1 \frac{1}{2} = \frac{3}{2}$$ $$1 \frac{1}{4} = \frac{5}{4}$$ 5. Find a common denominator to subtract the fractions. The least common denominator of 2 and 4 is 4. Convert $$\frac{3}{2}$$ to $$\frac{6}{4}$$. 6. Now subtract: $$\frac{6}{4} - \frac{5}{4} = \frac{1}{4}$$ 7. The difference is $$\frac{1}{4}$$ cups. **Answer:** The candle jar with the most pink wax has $$\frac{1}{4}$$ cups more wax than the jar with the least pink wax.
