The number of volunteers to walk dogs at the local animal shelter last year was 20 this year the number of volunteers has risen

Alex73 [517]

There is 150% increase in the number of volunteers.

Step-by-step explanation:

Given,

Old number of volunteers = 20

New number of volunteers = 50

Change = New value - Old value

Change = 50 - 20 = +30

The positive sign indicates the increase.

Percent increase = $\frac{Change}{Old\ value}*100\\$

$Percent\ increase=\frac{30}{20}*100\\\\Percent\ increase=\frac{3000}{20}\\\\Percent\ increase=150\%$

There is 150% increase in the number of volunteers.
