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

### Instruction:
John decided to sell his PlayStation to buy a new computer.  The computer's cost was $700 and the accessories cost was $200.  The PlayStation was worth $400 but he sold it for 20% less than its value.  How much money came out of his pocket?

### Response:
 Anapoteza 400 * .2 = $<<400*.2=80>>80 kwenye PlayStation
Hiyo inamaanisha aliinuza kwa 400 - 80 = $<<400-80=320>>320
Hivyo gharama ya kompyuta ilikuwa 700 + 200 = $<<700+200=900>>900
Hivyo alikuwa $900 - $320 = $<<900-320=580>>580 kutoka mfukoni mwake
