Question

Jake is eating dinner at a restaurant. The cost of his meal, including sales tax, is m dollars. After leaving an 18% tip, the amount Jake pays at the restaurant is represented by the following expression. In this expression, what does the term 0.18m represent?

Answer 1

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.

$tip = \frac {18 * m} {100}\\tip = 0.18m$

The amount Jake pays is represented by:

$m + 0.18m$

Where 0.18m is the tip

ANswer:

Tip
