Number of sandwiches sold on Monday = 30
Number of sandwiches sold on Tuesday = 20
Number of sandwiches sold on Wednesday = 10
Number of sandwiches sold on Thursday = 190
Number of sandwiches sold on Friday = 140
Number of sandwiches sold on Saturday = 120
Number of sandwiches sold on Sunday = 180
Number of more sandwiches sold on Sunday than on Tuesday
= 180 - 20
= 160
