Final answer:
To find the total cost of the meal including the tip, add the cost of the meal, sales tax, and tip.
Step-by-step explanation:
To find the total cost of the meal including the tip, we need to add the cost of the meal, the sales tax, and the tip.
- The cost of the meal is $54.20
- The sales tax is 6% of $54.20, which is $3.25
- The tip is 15% of $54.20, which is $8.13
- Add all three amounts together: $54.20 + $3.25 + $8.13 = $65.58
- The total cost, including the tip, is $65.58.
