At Ken's local store, a pound of steak is going for $7. He decides to get two pounds. At the till, he pays using a $20 bill. How much money will he get back? Let's be accurate as possible.

2 pounds of steak will cost Ken 2 * 7 = 14 dollars. Subtracting that amount from $20 will give 20 - 14 = 6 dollars. Ken will therefore get 6 dollars back.
The answer: 6.
