This would be a 500% increase.
6 x 1 = 6, and so this is a 0% increase of 6.
6 x 2 = 12, and so this is a 100% increase
6 x 3 = 18, and so this is a 200% increase.
Knowing this, we know that 36 is 600% of 6, or a 500% increase
Ok so like
Percent of change is the amount of change/original amount
The amount of change is 30 because 36-6=30
30/6 is 5
and
5 = 500% percent of change
