Two stores sell the same model of smartphone, but they offer it at different prices and with different discounts. Store A lists the smartphone at a full price of $125 and offers an additional discount of 8%.  Store B lists the same smartphone for $130 and offers an additional discount of 10%.  After both stores' discounts are applied, how much cheaper is store A's smartphone than store B's smartphone?
How much is the additional discount? ** Store A has a $125 x 8/100 = $<<125*8/100=10>>10 discount.
How much does the smartphone from store A cost? ** So the smartphone from store A will only cost $125 - $10 = $<<125-10=115>>115.
How much is the additional discount? ** Store B has a $130 x 10/100 = $<<130*10/100=13>>13 discount.
How much does the smartphone from store B cost? ** So the smartphone from store B will only cost $130 - $13 = $<<130-13=117>>117.
How much cheaper is store A's smartphone than store B's smartphone? ** Thus, store A's smartphone is $117 - $115 = $<<117-115=2>>2 cheaper than that of store B.
