My question is: Tony made a sandwich with two slices of bread for lunch every day this week. On Saturday, he was extra hungry from doing yard work and made two sandwiches. How many slices of bread are left from the 22-slice loaf Tony started with? Your thoughts:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

There are 7 days in a week, so Tony made 1 * 7 = 7 sandwiches. On Saturday, he made 1 extra sandwich, so he made 7 + 1 = 8 sandwiches this week. A sandwich has 2 slices of bread, so he used 8 * 2 = 16 slices. Thus, Tony has 22 - 16 = 6 slices of bread left. The final answer: 6.
