What is the unitary method?
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
The population of a city in 2005 was 36,000. By 2010, the city’s population had grown to 43,800 people.
The population of the city has grown exponentially since 2005 and continues to grow at the same rate,
2005 - 36000
2010 - 43800
2015 - 51600
43,800 - 36,000 = 7,800
43,800 + 7,800 = 51600.
Therefore, The answer would be 51600.
The population grows by 7,800 every five years.
