###Human: 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?, ### Assistant: Store A has a $125 x 8/100 = $10 discount.
So the smartphone from store A will only cost $125 - $10 = $115.
Store B has a $130 x 10/100 = $13 discount.
So the smartphone from store B will only cost $130 - $13 = $117.
Thus, store A's smartphone is $117 - $115 = $2 cheaper than that of store B. 
 So the answer is :  2
