Jon drinks a bottle of water that is 16 ounces every 4 hours for the 16 hours he is awake. Twice a day he also drinks a bottle that is 25% larger than those bottles. How much fluid does he drink a week? Let's be accurate as possible.
He drinks 16 / 4 = 4 of the small bottles each day. That is 4 * 16 = 64 ounces. The larger bottles are 16 * .25 = 4 ounces larger. So the large bottles are 16 + 4 = 20 ounces. So he drinks 20 * 2 = 40 ounces of those a day. So he drinks 64 + 40 = 104 ounces a day. That means he drinks 104 * 7 = 728 ounces a day.
The answer: 728.
