a) what was the population in 1905?
b) find the increas in population from 1895 to 1905.

What was the population in 1895?

2120, right? r u asking me that or r u wondering?? :S

You gave the population in 1805. But the problem wants you to compare the 1905 population with the 1895 figure.

ooo sorry. so would you do 2120 x 1.15? because you are figuring out 115% of 2120?

Yes. That's correct.

and then find the answer and subtract it from 2120?

wait... 2438  2120?

Yes. The population in 1905 was 2438.
2438  2120 = 318.
The population increased by 318 people between 1895 and 1905. 
ok thanks!
