How much money was the down payment? ** 100000(.20)=20000$ down payment
How much was left to pay after the down payment? ** 100000-20000=$<<100000-20000=80000>>80000 remaining
How much did Roger's parents pay off? ** 80000(.30)=24000
How much money does Roger still owe on his house? ** 80000-24000=<<80000-24000=56000>>56000$
