The original bill was valued at 106.67 $
if 25% was paid, and 80 dollars are left, this means that 80 dollars is 75% of the bill. 25% is a quater, and 75% is three quarters.
here, we can divide 80 into three parts ->
80 ÷ 3 ≈ 26.67
that means a quater of the bill is 26.67 $
if 80$ were left to be paid, just add the 26.67$ from the first quater ->
80 + 26.67 = 106.67 $
