(24/30)*100 = 80%

Therefore she decreased from 100% to 80%, which is about 20% decrease.
Thus, the answer is 20%

Another way to do this is.

[tex] \frac{(Original value - current value)}{Original value} * 100% = percentage of change in value[/tex]

Which in this case is
[tex] \frac{30-24}{30} * 100% = 20%[/tex]
