Acab ride from your home to the airport cost $23.47. if you want to tip the cab driver close to 10 percent of the fare, how much should you tip?

You would give the person
$2.35

I will show you my work
if you take the original #and multiply it by the % that you may want to tip you will get your end result.

23.47x 10%= 2.347
in this case because it has  decimal points we will round.
because 7 is number greater than 4 you will round the decimal point up.
in which case you get exactly $ 2.35
