William gave the cashier at Billy Bob’s BBQ two $20-dollar bills to pay for 4 chopped beef sandwiches to go. The cashier gave him $6.84 in change.
What is the cost in dollars and cents for a chopped beef sandwich?
Each chopped beef sandwich costs $7.29 (20 - 6.84 = 13.16, 13.16 / 4 = 3.29, 3.29 + 4 = 7.29).
Therefore, the cost for a chopped beef sandwich is $7.29.
