1. **State the problem:** Lou and Jacob each sold 200 pieces of jewelry. Lou sold 20% of her sales as rings, and Jacob sold 35 rings. We need to find who sold more rings and by how many. 2. **Calculate the number of rings Lou sold:** Lou's rings = 20% of 200 = $0.20 \times 200$ 3. **Calculate Lou's rings:** $$0.20 \times 200 = 40$$ 4. **Compare Lou's rings to Jacob's rings:** Lou sold 40 rings, Jacob sold 35 rings. 5. **Find who sold more and by how many:** $$40 - 35 = 5$$ Lou sold 5 more rings than Jacob. 6. **Check the percentage difference:** Percentage more rings Lou sold compared to Jacob: $$\frac{40 - 35}{35} \times 100 = \frac{5}{35} \times 100 = 14.29\%$$ **Final answer:** Lou sold more rings than Jacob by 5 rings, which is approximately 14.29% more rings.
