Final answer:
To find the total cost of Nathan's meal including a 23% tip on a $65 bill, calculate the tip amount by multiplying 0.23 by $65, which is $14.95. Add this tip to the original bill to determine the total cost, which is $79.95.
Step-by-step explanation:
The question involves calculating the total cost of a meal at a restaurant including a given percentage for the tip. Nathan's bill before the tip is $65, and he wishes to leave a 23% tip.
First, we need to calculate the amount of the tip by converting the percentage to a decimal (23% becomes 0.23) and then multiplying it by the cost of the meal:
Tip amount = 0.23 × $65 = $14.95
Next, we add the tip amount to the original bill to find the total cost:
Total cost = $65 + $14.95 = $79.95
Therefore, the total cost of the meal, including the tip, would be $79.95, which corresponds to option A.
