Question

The town of new London uses about 2,750,000 gallons of water each month. If the population of new London is approximately 61,000, which of the following provides the best estimate of the number of gallons of water used per person each month?

Answer 1

45 gallons of water used per person each month

Solution:

Given that,

The town of new London uses about 2,750,000 gallons of water each month

The population of new London is approximately 61,000

To find: Number of gallons of water used per person each month

From given,

Total gallons of water each month = 2750000

Population = 61000

Therefore,

$Gallons\ of\ water\ per\ person = \frac{\text{Total gallons of water each month}}{population}$

$Gallons\ of\ water\ per\ person = \frac{2750000}{61000}\\\\Gallons\ of\ water\ per\ person = \frac{2750}{61}\\\\Gallons\ of\ water\ per\ person =45.08 \approx 45$

Thus 45 gallons of water used per person each month
