<human>:  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?
<bot>: How many sandwiches did Tony make? ** There are 7 days in a week, so Tony made 1 * 7 = <<1*7=7>>7 sandwiches.
How many sandwiches did Tony make this week? ** On Saturday, he made 1 extra sandwich, so he made 7 + 1 = <<7+1=8>>8 sandwiches this week.
How many slices of bread did Tony use? ** A sandwich has 2 slices of bread, so he used 8 * 2 = <<8*2=16>>16 slices.
How many slices of bread are left? ** Thus, Tony has 22 - 16 = <<22-16=6>>6 slices of bread left.
