1. **State the problem:** We need to find how much taller the 7-year-old bush is compared to the 4-year-old bush based on the scatter plot data. 2. **Identify the heights from the scatter plot:** - Height of 7-year-old bush is approximately 24 inches. - Height of 4-year-old bush is not explicitly given, but we can estimate it by interpolating between points near age 3 (12 inches) and age 5 (16 inches). 3. **Estimate height of 4-year-old bush:** Since 4 is halfway between 3 and 5, we can average the heights: $$\frac{12 + 16}{2} = \frac{28}{2} = 14$$ inches. 4. **Calculate the difference in height:** $$24 - 14 = 10$$ inches. 5. **Answer:** The 7-year-old bush is 10 inches taller than the 4-year-old bush.
