B Correct answer
Explanation

Total price including 15% gratuity is 207. Price before gratuity = 207 / 1.15 = 180. Average price per person = 180 / 15 = 12.

AI explanation

To find the base price before the 15 percent gratuity, divide the total bill by 1.15. The calculation is 207.00 dollars divided by 1.15, which equals 180.00 dollars. This 180.00 dollars is the total price of the lunches excluding the gratuity, so you divide this amount by the 15 people to find the individual average. The final average price per person is 180.00 dollars divided by 15, which is 12.00 dollars.
