Increasing the original price of a certain item by 30 percent and then increasing the new price by 30 percent is equivalent to increasing the original price by what percent?  Choose the correct choice from the following choices:
A) 31.25
B) 37.5
C) 50.0
D) 52.5
E) 69.0
We're told that the original price of an item is increased by 30% and then THAT price is increased by 30%....   IF....   Starting value = $100   + 30% = 100 + .30(100) = 130   + 30% = 130 + .30(130) = 130 + 39=

169   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:   59/100 = 69%   Final Answer:   69.0
