1. **State the problem:** We want to find the fraction of Juan's shifts where total sales were $225$ or more based on the given box plot. 2. **Understand the box plot:** The box plot shows total sales per shift with: - Minimum (left whisker) around $100$ - Lower quartile (start of box) just above $125$ - Median near $200$ - Upper quartile (end of box) about $225$ - Maximum (right whisker) about $250$ 3. **Recall box plot quartiles:** - The box covers the middle 50% of data (from Q1 to Q3). - Left whisker to Q1 covers the lowest 25%. - Q3 to right whisker covers the highest 25%. 4. **Locate $225$ on the plot:** $225$ is at the upper quartile (Q3). 5. **Interpretation:** - Data points at or above $225$ are in the top 25% of shifts. 6. **Answer:** The fraction of shifts with sales $225$ or more is $\frac{1}{4}$ or $0.25$. **Final answer:** $$\boxed{\frac{1}{4}}$$
