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

### Instruction:
John writes 3 stories every week.  Each short story is 50 pages.  He also writes a novel that is 1200 pages each year.  Each sheet of paper can hold 2 pages.  Over 12 weeks, how many reams of paper does he need to buy if a ream contains 500 sheets?

### Response:
 Anaandika kurasa 3*50=<<3*50=150>>150 kila wiki.
Hii inamaanisha anaandika kurasa 150*52=<<150*52=7800>>7800 za hadithi fupi kwa mwaka.
Hivyo anaandika jumla ya kurasa 7800+1200=<<7800+1200=9000>>9000 kwa mwaka.
Hivyo anahitaji karatasi 9000/2=<<9000/2=4500>>4500.
Hii inamaanisha anahitaji masanduku 4500/500=<<4500/500=9>>9 ya karatasi.
