    Original cost 80 and new cost 110 

    Percentage increase: (110-80)/80 times 100 = 37.5%

    Clearly the new value is larger than the original so it is an increase.

    Percent Change = [(New Value - Old Value) / (Old Value)] x 100

                               = [(110 - 80) / 80] x 100 = 30/80 x 100 = 37.5 % Increase
