what was the price of the earphones before the tax was added?

a.

Let us assume the original cost of the earphones = x dollars
Then
x * (106/100) = 13.25
x = 13.25 * (100/106)
   = 1325/106
   = 12.50 dollars
So the actual cost of the earphones was $12.50. The correct option among all the options that are given in the question is the second option or option "B".
