### Instruction:
A thirsty traveler found an oasis in the desert. He drank 32 ounces of water. His camel drank seven times as much as he did. There are 128 ounces in a gallon. How many gallons of water did they drink altogether?

### Response:
The traveler's camel drank 32*7 = <<32*7=224>>224 ounces of water
The traveler and his camel drank 32+224 = <<32+224=256>>256 ounces
256 ounces is 256/128 = <<256/128=2>>2 gallons
They drank a total of 2 gallons of water altogether.
