Percent increase #= 32%#

Explanation:

First, let's evaluate what percentage of #12,250# gives #16,170#:

#=> (12,250) / (100) cdot x = 16,170#

#=> 122.5 x = 16,170#

#=> x = 132%#

This means that #132%# of #12,250# is equal to #16,170#.

#100%# of any number is equal to that number.

#=> 100%# of #12,250 = 12,250#

So if we added #32%# of #12,250# to itself, we would get #16,170#.

Therefore, the percent increase is #32%#.
