Answer: 300%
Step-by-step explanation:
percent of increase: new/old×100%-100%
Since it is percent of increase, you need to subtract the original percent (100%) from the current percent.
------------------
new (current)=2000
old (original)=500
new/old×100%-100%
=2000/500×100%-100%
=4×100%-100%
=400%-100%
=300%
