The way I figure it --
Ten percent of 20 = 2. Double that and the tip comes out to a little over $4.
To estimate a 20% tip on a taxi ride that costs $21.30, you can follow these steps:
1. Start by calculating 20% of the taxi fare. To do this, divide the fare by 100 and then multiply the result by 20.
(20 / 100) * $21.30 = $4.26
2. This means that the estimated tip amount is $4.26.
So, an estimated 20% tip on a taxi ride that costs $21.30 would be $4.26.
