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