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?
The total horse he owns is 5+3= <T>add(5, 3)=8
The total liters of water each horse consumes is 5 + 2= <T>add(5, 2)=7
So, the total water all the horses consume every day is 7 x 8 = <T>multiply(7, 8)=56
And the total of liters of water they consume every week is 56 x 7 = <T>multiply(56, 7)=392
Therefore, the total liters of water they consume for the entire month is 392 x 4= <T>multiply(392, 4)=1568
