Your friends are eating at the
same restaurant, and their bill
adds up to $45. They leave a $9
tip for their server. What
percentage of the bill was the
server's tip? Explain your
reasoning

Respuesta :

The tip was 20% of the bill since if you do 9x5 that equals 45 and since 45 it the whole bill that makes it 100% and 9 is only 1/5 so that makes 9 20%
