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?

How much will two pounds of steak cost? ** 2 pounds of steak will cost Ken 2 * 7 = <<2*7=14>>14 dollars
How much money will Ken get back? ** Subtracting that amount from $20 will give 20 - 14 = <<20-14=6>>6 dollars
How much money will Ken get back? ** Ken will therefore get 6 dollars back.
