Question 110544
Percent of increase is when amount goes up;
lets say you need to know the percent of increase when an amount of an item changes from $1.18 to 1.38,so you subtract new amount from original amount and divide that by original amount; 
{{{percent increase = 100  (0.20/1.18)}}}
% increase = 100 * 0.169 = 16.9%
