Calculation of Population Increase

To calculate the population increase in the city block from 2008 to 2010, we need to consider the percentage increases in both 2009 and 2010 compared to the previous year.

In 2009, the population increased by 17% compared to 2008. In 2010, the population increased by 18% compared to 2009.

Let's calculate the population in each year:

- Population in 2008: 40,000 - Population in 2009: 40,000 + (17% of 40,000) - Population in 2010: (Population in 2009) + (18% of (Population in 2009))

Calculation Steps:

1. Calculate the population increase in 2009: - Population increase in 2009 = 17% of 40,000 - Population increase in 2009 = 0.17 * 40,000 - Population increase in 2009 = 6,800

2. Calculate the population in 2009: - Population in 2009 = Population in 2008 + Population increase in 2009 - Population in 2009 = 40,000 + 6,800 - Population in 2009 = 46,800

3. Calculate the population increase in 2010: - Population increase in 2010 = 18% of Population in 2009 - Population increase in 2010 = 0.18 * 46,800 - Population increase in 2010 = 8,424

4. Calculate the population in 2010: - Population in 2010 = Population in 2009 + Population increase in 2010 - Population in 2010 = 46,800 + 8,424 - Population in 2010 = 55,224

Therefore, the population in the city block in 2010 was 55,224 people.
