Respuesta :
For this case we must obtain the total amount of the bills:
[tex]23.59 + 40.65 + 30.50 + 15.68 = 110.42[/tex]
Thus, the total of the bills was $ 110.42.
We make a rule of three to determine the percentage of tips received:
$ 110.42 -----------> 100%
$ 17.67 ------------> x
Where the variable "x" represents the percentage of tips received.
[tex]x = \frac {17.67 * 100} {110.42}\\x = 16.0025[/tex]
So, he received 16% tip.
