1. The problem is to determine which filter design meets both requirements: - Remove at least 95% of chlorine from tap water. - Be less than 12 centimeters wide. 2. We analyze each design based on the two criteria: - Design A: 95% removal, 13.1 cm width - Design B: 96% removal, 12.4 cm width - Design C: 93% removal, 10.2 cm width 3. Check chlorine removal: - Design A meets the 95% removal requirement. - Design B meets the 95% removal requirement. - Design C does not meet the 95% removal requirement (only 93%). 4. Check width: - Design A is 13.1 cm, which is not less than 12 cm. - Design B is 12.4 cm, which is not less than 12 cm. - Design C is 10.2 cm, which is less than 12 cm. 5. Combine both requirements: - Design A fails width requirement. - Design B fails width requirement. - Design C fails chlorine removal requirement. 6. Conclusion: None of the designs meet both requirements simultaneously. Final answer: No design satisfies both requirements of at least 95% chlorine removal and width less than 12 cm.
