<human>:  On Monday Samson ate 3 sandwiches at lunch and ate twice as many at dinner. The next morning, he felt sick from eating all those sandwiches, so he only ate one sandwich for breakfast. How many more sandwiches in total did Samson eat on Monday than Tuesday?
<bot>: How many sandwiches did Samson eat at dinner on Monday? ** Samson ate 3 sandwiches x 2 = <<3*2=6>>6 sandwiches at dinner on Monday
How many sandwiches did Samson eat on Monday? ** He ate 3 sandwiches + 6 sandwiches = <<3+6=9>>9 sandwiches total on Monday
How many more sandwiches in total did Samson eat on Monday than Tuesday? ** Therefore, he ate 9 sandwiches - 1 sandwich = 8 more sandwiches on Monday than Tuesday
