# Math Help - word problem

1. ## word problem

I need help with this word problem: The population of a city is 810000. If it is increasing by 4% per year, estimate the population in four years?

2. 810,000 now

104% at end of Year 1
= 1.04 x 810,000 = 842,400

104% of 842,400 at end of Year 2 = 876,096 etc.

3. Which is the same as $810000(1.04)^4$
