For this case we have that variable "m" represents the cost of Jake's food. They tell us that he left an 18% tip. That is to say:
m -------------> 100%
tip ------------> 18%
Where "tip" is the cost of the tip based on the cost of the meal.
[tex]tip = \frac {18 * m} {100}\\tip = 0.18m[/tex]
The amount Jake pays is represented by:
[tex]m + 0.18m[/tex]
Where 0.18m is the tip
ANswer:
Tip
