Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Nyumba yake ya zamani iligharimu $2*750=$<<2*750=1500>>1500 kwa mwezi
Nyumba yake mpya inagharimu $2800/2=$<<2800/2=1400>>1400 kwa mwezi
Hivyo anaokoa $1500-$1400=$<<1500-1400=100>>100 kwa mwezi
Hiyo inamaanisha anaokoa $100*12=$<<100*12=1200>>1200 kwa mwaka
