We're told that the original price of an item is increased by 15% and then THAT price is increased by 25%....   IF....   Starting value = $100   + 15% = 100 + .15(100) = 115   + 25% = 115 + .25(115) = 115 + 28.75=

143.75   The question asks how the final price relates to the original price. This is essentially about Percentage Change, which means we should use the Percentage Change Formula:   Percentage Change= (New - Old)/Old = Difference/Original   Doing either calculation will yield the same result:   43.75/100 = 43.75%   Final Answer:   43.75
