Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
The number of Greek yogurt packs that had expired is 40/100*80 = <<40/100*80=32>>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 = $<<12*32=384>>384
