John decides to get a new apartment with a roommate. His former rent was $2 per square foot for a 750 square foot apartment. His new apartment cost $2800 per month, which he splits evenly with the roommate. How much money does he save a year? Give me reasons, before answering the question

His old apartment cost 750 * $2 = $1500 a month. His new apartment cost $2800 / 2 = $1400 a month. So he saves $1500 - $1400 = $100 a month. That means he saves $100 * 12 = $1200 a year. So the final answer is 1200.
