After the 6.5% tax was added, the bill was ...
$12.70 × (1 +0.065) = $13.5255 ≈ $13.53
<h3>tip</h3>
After the 18% tip was added to this amount, the total cost was ...
$13.53 × (1 +0.18) = $15.9654 ≈ $15.97
<h3>total</h3>
Then the multiplier of the original bill was ...
$15.97/$12.70 ≈ 1.25748... ≈ (1 +25.7%)
The total cost was about 26% more than the original bill.
