[Question]Ivar owns a stable. He recently has 3 horses and each horse consumes 5 liters of water for drinking and 2 liters for bathing per day. If he added 5 horses, how many liters of water does Ivar need for all the horses for 28 days?
[Answer]The total horse he owns is 5 + 3 = 8. The total liters of water each horse consumes is 5 + 2 = 7. So, the total water all the horses consume every day is 7 x 8 = 56. And the total of liters of water they consume every week is 56 x 7 = 392. Therefore, the total liters of water they consume for the entire month is 392 x 4 = 1568. The answer is 1568.
