Nathaniel has 11 tickets to a basketball game. He gives away 2 tickets each to his best friends, until he only has 3 tickets left. How many best friends does Nathaniel have? Give me reasons, before answering the question

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Nathaniel gave away 11 - 3 = 8 tickets to his best friends. Nathaniel has 8 / 2 = 4 best friends. So the final answer is 4.
