James has 3 gallons of milk. He drank 13 ounces of the milk. If there are 128 ounces in a gallon, how many ounces of milk does James have left? Let's think first. Chain of thought:
First find out how many ounces of milk James had to begin with by multiplying the number of gallons by the number of ounces per gallon: 3 gallons * 128 ounces / gallon = 384 oz. Now subtract the 13 ounces James drank from the initial amount of milk: 384 oz - 13 oz = 371 oz.
Therefore, the answer is 371.
