<human>:  Roger bought a house for $100,000. He was able to pay 20% down, and his parents paid off an additional 30% of the remaining balance. How much money does Roger still owe on his house?
<bot>: How much money was the down payment? ** 100000(.20)=20000$ down payment
How much was left to pay after the down payment? ** 100000-20000=$<<100000-20000=80000>>80000 remaining
How much did Roger's parents pay off? ** 80000(.30)=24000
How much money does Roger still owe on his house? ** 80000-24000=<<80000-24000=56000>>56000$
