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

### Instruction:
Six Grade 4 sections launched a recycling drive where they collect old newspapers to recycle. Each section collected 280 kilos in two weeks. After the third week, they found that they need 320 kilos more to reach their target. How many kilos of the newspaper is their target?

### Response:
 Kwa wiki, kila darasa lilikusanya 280/2 = <<280/2=140>>140 kilo za magazeti.
Hivyo, katika wiki tatu, darasa moja lilikusanya 140 x 3 = <<140*3=420>>420 kilo.
Hivyo, madarasa manne yalikusanya jumla ya 420 x 4 = <<420*4=1680>>1680 kilo.
Hivyo, lengo lao ni kukusanya 1680 + 320 = <<1680+320=2000>>2000 kilo za magazeti.
