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:
[tex]\frac{New-Old}{Old}*100[/tex]
Where old is 320 and new is 349. Lets substitute and find the increase (percentage):
[tex]\frac{New-Old}{Old}*100\\=\frac{349-320}{320}*100\\=\frac{29}{320}*100\\=9.0625[/tex]
The percentage increase is 9.0625%
