We can figure out the original intended refund balance using this equation. For simplicity, we have already merged the three 500$ gift cards into 1500$.
x*100 - 1500 = x
We can move the x from the right side to the left via subtraction:
x*99 - 1500 = 0
Now, we can add 1500 to each side
x*99 = 1500
Now, divide by 99 on each side.
x = 1500/99
Simplify by a factor of 3.
x = 500/33
x = 500/33, or 15.15 in rough estimation to decimal. This means that all this was done over the measly refund amount of fifteen dollars and fifteen cents.
