To find the percentage of the original bill that was the tip, you can follow these steps:

1. Calculate the amount of the tip: Original bill amount - Extra left for the tip
Tip = $27.20 - $3.81 = $23.39

2. Calculate the percentage of the tip: (Tip amount / Original bill amount) x 100%
Percentage = (23.39 / 27.20) x 100% = 85.85%

Therefore, the tip represents approximately 85.85% of the original bill.
