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

### Instruction:
Tom needs to buy a new gaming system.  He trades in his super Nintendo for an original NES.  The SNES is worth $150 and the store gives him 80% of that value.  He gives $80 and gets back $10 change and a game worth $30.  How much was the NES on sale for?

### 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
