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

### Instruction:
 Alice anataka karatasi 1000 zilizofungwa kuwa ndege. Yeye hufunga nusu yake mwenyewe, na rafiki hufunga wa tano wa karatasi zilizobaki kwa ajili yake. Alice bado anahitaji kufunga karatasi ngapi?


### Response:
 Alice hufunga ndege 1000 * 0.5 = <<1000*0.5=500>>500 ndege yeye mwenyewe.
Hii inaacha ndege 1000 - ndege 500 = <<1000-500=500>>500 zilizobaki kufungwa.
Rafiki hufunga wa tano wa idadi iliyobaki, hivyo wamefunga ndege 500 / 5 = <<500/5=100>>100 kwa ajili yake.
Hii inamaanisha kuna jumla ya ndege 500 + ndege 100 = <<500+100=600>>600 zimefungwa.
Hivyo, Alice bado anahitaji kufunga ndege 1000 - ndege 600 = <<1000-600=400>>400.
