The population of a town was 47,000 in 1950 and 83,000 in 2010. Assume the rate of population increase is constant.
What will the population be in 2015?
Question 3 options:
86,000
83,600
85,400
89,000
To calculate the population in 2015, we need to determine the rate of population increase first.
The population increase from 1950 to 2010 is 83,000 - 47,000 = 36,000.
The time span between 1950 and 2010 is 2010 - 1950 = 60 years.
To calculate the rate of population increase per year, we divide the population increase by the number of years:
36,000 / 60 = 600.
Now we can calculate the population in 2015 using the constant rate of increase:
2015 - 1950 = 65 years
47,000 + (65 * 600) = 47,000 + 39,000 = 86,000.
Therefore, the population in 2015 will be 86,000.
