Question

A group of three friends has just finished a celebration dinner at a nice restaurant. They decide to leave a 20% tip for the server. Tiana and Roy are married, and are paying together. Tiana and Roy had big dinners and wine, and their orders together cost $100. Shaun is a vegetarian, and had a big bowl of vegetable bean soup and juice, for a total of $15.

If they split the tip proportionally, how much of the tip should Tiana and Roy pay? $

How much of the tip should Shaun pay?
$

What percentage of the total tip will Shaun pay?
%

Answer 1

Explanation:

Tiana and Roy had a total of $100. 20% would be $20

Shaun's meal was $15. 20% would be $3

Total tip would be $115 x 20% = $23

Tiana & Roy's portion of the tip is 100/115 or 87%

Shaun's portion of the tip is 15/115 or 13%
