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

So, the elephant drank (2560-1944=614) 616 liters of water in two weeks. How many is that per day?

we divide: 616/14=44!

so the elephant drinks 44 liters of water per day.

now, how many full days are there in a tank of 2560 liters?

we have to divide again:

2560/44= 58 and 8/44 left.

but 8/44 is not enough for a day, and the question only asks for full days: so we can 58!

The answer would be d i think but i’m for sure it is not a and c
