Final answer:
When a price floor of $10 per pound is imposed on all 1-pound bags of coffee, it could potentially cause more people to buy fair-trade coffee.
Step-by-step explanation:
When a price floor of $10 per pound is imposed on all 1-pound bags of coffee, it means that the price of both standard and fair-trade coffee cannot fall below $10 per pound.
Since the price of fair-trade coffee is already higher than $10 per pound ($12), this policy would not affect the price of fair-trade coffee. However, it might lead more people to buy fair-trade coffee because the price difference between standard coffee ($8) and fair-trade coffee ($12) would decrease. Some consumers may decide to switch to fair-trade coffee since the price is now closer to that of standard coffee.
Therefore, this policy could potentially cause more people to buy fair-trade coffee.
