[Reveal] Spoiler:
How come the answer is B?
This is how I solved it and got A, which is incorrect.
$207 includes 15% gratuity so 0.15 * 207 = 31.05
Price EXCLUDING gratuity = 207 - 31.05 = 175.95
Average price per person = 175.95/15 = 11.73

let x be the total without gratuity.. then we shall form
x+0.15x
