To find the percentage of a tip relative to the total meal cost, you can follow these steps:
-
Calculate the total cost of the meal including the tip. \[ \text{Total Cost} = \text{Meal Cost} + \text{Tip} = 17.95 + 3.00 = 20.95 \]
-
Calculate the percentage of the tip. \[ \text{Tip Percentage} = \left( \frac{\text{Tip}}{\text{Total Cost}} \right) \times 100 \] Substituting the values: \[ \text{Tip Percentage} = \left( \frac{3.00}{20.95} \right) \times 100 \]
-
Calculate the value: \[ \text{Tip Percentage} = \left( 0.143 \right) \times 100 \approx 14.3% \]
Therefore, you are leaving approximately 14.3% as a tip.
