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

### Instruction:
Jim decides to buy mayo in bulk.  He can buy 1 gallon of mayo at Costco for 8 dollars.  At the normal store, a 16-ounce bottle costs $3.  How much money does he save by buying the gallon container?

### Response:
A gallon is 1*128=<<1*128=128>>128 ounces
So he needs to buy 128/16=<<128/16=8>>8 of the small bottles
That would cost 8*3=<<8*3=24>>24 dollars
So he saves 24-8=<<24-8=16>>16 dollars
