Please answer the following question by reasoning step-by-step.
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?

6
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.

.

So, the final answer is 6
