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

### Instruction:
 Tom anahitaji kununua mfumo mpya wa michezo. Anabadilisha Super Nintendo yake na NES ya awali. SNES ina thamani ya $150 na duka linampa 80% ya thamani hiyo. Anatoa $80 na anapata $10 kama mabadiliko na mchezo wenye thamani ya $30. NES ilikuwa inauzwa kwa bei gani?


### Response:
 Anapata 150*.8=$<<150*.8=120>>120 kwa kubadilisha SNES
Anabadilisha hiyo na anatoa $80 hivyo ni 120+80=$<<120+80=200>>200
Anapata 10+30=$<<10+30=40>>40 kama mabadiliko
Hivyo, NES iligharimu 200-40=$<<200-40=160>>160
