First, let's write this as an equation.


f(x)= price of an item


p= percent increase


f(x)=xp^2


1.44x=xp^2


1.44=p^2


√( 1.44)= \sqrt{p^2


p=1.2


1.2=120%

Answer: The second price was a
120% of the first price which means that the second increase was 20% more than the first price.

Hope this helps!
