Number of puffs sold on Monday = 280
Number of puffs sold on Tuesday = 120
Number of puffs sold on Wednesday = 70
Number of puffs sold on Thursday = 50
Number of puffs sold on Friday = 60
Number of puffs sold on Saturday = 40
Number of puffs sold on Sunday = 200
Number of more puffs sold on Sunday than on Tuesday
= 200 - 120
= 80
