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

### Instruction:
 Duka linauza kompyuta mpakato kwa $600 kila moja na simu ya mkononi kwa $400. Celine ananunua kompyuta mbili na simu za mkononi nne kwa ajili ya watoto wake. Anapata pesa ngapi kama ana $3000?


### Response:
 Gharama ya kompyuta mbili ni 2 x $600 = $<<2*600=1200>>1200.
Gharama ya simu za mkononi nne ni 4 x $400 = $<<4*400=1600>>1600.
Hivyo, gharama jumla ya vitu vyote ni $1200 + $1600 = $<<1200+1600=2800>>2800.
Hivyo, Celine anapata pesa ya kubadilisha $3000 - $2800 = $<<3000-2800=200>>200.
