<human>:  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?
<bot>: How much did John's old apartment cost? ** His old apartment cost 750*$2=$<<750*2=1500>>1500 a month
How much does John's new apartment cost? ** His new apartment cost $2800/2=$<<2800/2=1400>>1400 a month
How much money does John save a month? ** So he saves $1500-$1400=$<<1500-1400=100>>100 a month
How much money does John save a year? ** That means he saves $100*12=$<<100*12=1200>>1200 a year
