At Furnace Woods School, enrollment increased from 320 students in 2006 to 349 students in 2007. What is the percent increase in

drek231 [11]

Answer:

9.0625%

Step-by-step explanation:

It increased from 320 to 349

This is a percent INCREASE.

320 is the "old" value and 349 is the "new" value.

We find percent increase by the formula:

$\frac{New-Old}{Old}*100$

Where old is 320 and new is 349. Lets substitute and find the increase (percentage):

$\frac{New-Old}{Old}*100\\=\frac{349-320}{320}*100\\=\frac{29}{320}*100\\=9.0625$

The percentage increase is 9.0625%
