The maximum amount of water that can be used by each house on a daily basis is 100 liters.
<h3>How to calculate the amount of water?</h3>
From the information given, the gated community consists of 40 houses and requires 500 liters of water everyday for common utilities of the community.
The maximum amount of water that can be used by each house on a daily basis will be:
4500 = 40x + 500
40x = 4500 - 500
40x = 4000
x = 4000/40
x = 100
