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 rate is (32,800 - 18,000) = 14,800 per 5 years 
therefore : 
in 2015 = 2010 + 5 years 
the pop. will be : 
32,800 + 14,800 = 47,600 

Hope this helped☻

Answer 2

47,600 is the answer all you have to do is subtract 18000 from32800 and the add the difference to 32800
