The percentage of change: This is how you set it up
% change = (New old value) =
(Old value) = x 100 %
40 is the old value and 72 is is the new value
The new value is greater than the old value.
(72 - 40) /40)x 100 = 80 or 80%
the percent change from 40 to 72 represents a positive change (increases) of 80.
