After 25% of a bill is paid $80 still remains to be paid. how much was the bill?

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 $
