Bob ordered 80 packs of Greek yogurt from Costco to use for the month. However, when the delivery arrived, he realized 40% of the packs were expired. He decided to return those packs. If each pack was $12, how much was Bob refunded for the expired product? Let's think first. Chain of thought:
The number of Greek yogurt packs that had expired is 40 / 100 * 80 = 32. If each pack of Greek yogurt was sold at $12, for the 32 packs of greek yogurt that he returned, Bob was refunded $12 * 32 = $384.
Therefore, the answer is 384.
