(a)
Number of puffs sold on Monday = 100
Number of puffs sold on Tuesday = 40
Number of puffs sold on Wednesday = 50
Number of puffs sold on Thursday = 110
Number of puffs sold on Friday = 130
Number of puffs sold on Saturday = 20
Number of puffs sold on Sunday = 200
Number of more puffs sold on Sunday than on Tuesday
= 200 - 40
= 160
