The elephant water tank hold 2560 gallons of water. after two weeks the zookeeper measures and find that the tank has 1944 gallons of water left. if the elephant drinks the same amount of water each day, how many days will of a full tank of water last?

The answer as a whole number is 58 days. The exact answer is 58.18 repeating. All you have to do is 2560-1944=616. Then you divide 616 by 14 which gives you 44. So the elephant is drinking 44 gallons a day. Then all you do is divide 2560 by 44, which gives you 58.18 repeating.
