Question

The population of a city in 2005 was 18,000. By 2010, the city’s population had grown to 32,800. If the population growth follows a linear model, what is the projected population for 2015?

Answer 1

The projected population for 2015 should be 47,600. 32,800-18,000=14,800 so 14,800 times 3 is 47,600. Hope this helped :)
