Jonas and Norma's restaurant bill comes to $23.40. They are planning to tip the waiter 15% of there bill. How much money should they leave for a tip

Respuesta :

They should leave $3.51 for a tip.  So half of $23.40 is $11.70, half of $11.70 is $5.85, and then a fifth of $5.85 is $1.17, then multiply $1.17 by 3.
$23.40x15% = $3.51 they should leave $26.91
