Question

For large parties a restaurant adds a 15% tip to the bill, how much would be added to a bill of $638.40? And not including the tax what would their total be?

Answer 1

15 % tip on bill of 638.40$

so the amount of tip is

`\begin{gathered} =638.40*(15)/(100) \\ =95.7\text{ \$} \end{gathered}`

the total amount would be

638.40 $ + 95. 7 $ = 734 .10 $

so the total is 734.10 $
