Question

The manager of a public pool is counting the people who came to swim in June and July. There were 600 people who came in June. There were 800 people who came in July. What is the percent increase in people who came from June to July?
25%


200%


3313%


75%

Answer 1

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:
$\frac{y -x}{x} = percent\ increase$

Substitute.
$\frac{800 - 600}{600} = percent\ increase$
$\frac{200}{600} \ or\ \frac{1}{3} = percent\ increase$

The percent increase in people from June to July is 33.3333333%, which is not one of the options you put there.
