Final answer:
Han's orange juice mixture tastes stronger compared to Clare's because Han's mixture has a higher ratio of orange juice concentrate to water.
Step-by-step explanation:
To determine whose orange juice mixture tastes stronger, we can compare the ratios of orange juice concentrate to water in each mixture. Clare's mixture has a ratio of 13 cups of orange juice concentrate to 212 cups of water, which simplifies to approximately 0.0613. Han's mixture has a ratio of 14 cups of orange juice concentrate to 123 cups of water, which simplifies to approximately 0.1138. Since Han's ratio is higher, it means that Han's orange juice mixture tastes stronger compared to Clare's.
