There is 10% increase in the size of the graduating class.
Step-by-step explanation:
Given,
Number of graduating students in 2010 = Old value = 160
Number of graduating students this year = New value = 176
Change = New value - Old value
Change = 176 - 160 = +16
The positive sign indicates the increase.
Percent increase = [tex]\frac{16}{160}*100[/tex]
Percent increase = [tex]\frac{1600}{160}[/tex]
Percent increase = 10%
There is 10% increase in the size of the graduating class.
