Question

Albert uses 8 liters if water to wash a car and spills an addititional liter per 2 cars. What would be the total amount of water needed to wash 4 cars?

Answer 1

the total amount is 16 liters of water

Answer 2

It takes 8 liters to wash each car. So 4*8 is 32 liters. But Albert spills water too because he is clumsy. So each time he washed 2 cars, he spills a liter of water. He washed 4 cars so he spilled 2 additional liters of water. 32+2=34.
34 liters of water
