Question

The population of a city in 2005 was 18,000. By 2010 the city's population had grown to 45,000. Economists have determined that the population growth follows an exponential model. If they are correct, what is the projected population for 2015?​

Answer 1

Step-by-step explanation:

First we have to find percent change by doing change/original

To find change: 45000-18000=27000

Now divide by original. 27000/18000=1.5

The change was 150 percent. Now we multiply 45000 by 150 percent to get the projected population for 2015.

45000*1.5=67500 people
