Answer :
So,
The percent increase is basically the same as percent decrease except that you subtract the June count from the July count. If you let x be the June count and y be the July count, you can write it mathematically as follows:
[tex] \frac{y -x}{x} = percent\ increase[/tex]
Substitute.
[tex] \frac{800 - 600}{600} = percent\ increase[/tex]
[tex] \frac{200}{600} \ or\ \frac{1}{3} = percent\ increase[/tex]
The percent increase in people from June to July is 33.3333333%, which is not one of the options you put there.
