Answer:

8000 gallons/household per month

Step-by-step explanation:

Given that the discharge of 4.8 trillion gallons could supply country A households in 6 months, find for a single month.

Divide the discharge (4.8 trillion gallons) by 6

4.8/6 =0.8 trillion gallons supplied to country,s households in 1 month

To find usage per household, divide the supply per month by the number of households

=0.8 × 1000,000,000,000 gallons/100,000,000 households

=0.8×10,000 gallons/household

=8000 gallons/household per month
