12 x 3 = 36 so im gonna say the percent change is going up by 2 because you already have 12.

actually the correct method is :

difference between change = 36 -12 = 24

% change = amount of change / original value then the value obtained to be multiplied by 100

so..... % change = 24 / 12 × 100
= 2 × 100
= 200 %


hope it helped !!! :)
