Number of puffs sold on Monday = 80
Number of puffs sold on Tuesday = 30
Number of puffs sold on Wednesday = 20
Number of puffs sold on Thursday = 180
Number of puffs sold on Friday = 200
Number of puffs sold on Saturday = 150
Number of puffs sold on Sunday = 120
Number of more puffs sold on Sunday than on Tuesday
= 120 - 30
= 90
