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

### Instruction:
Roger bought a house for $100,000.  He was able to pay 20% down, and his parents paid off an additional 30% of the remaining balance.  How much money does Roger still owe on his house?

### Response:
 100000(.20)=20000
100000-20000=$<<100000-20000=80000>>80,000
80,000(.30)=24,000
80,000-24,000=<<80000-24000=56000>>56,000
