The line graph shows the number of puffs sold in a week.
- How many more puffs were sold on Sunday than on Tuesday?
- On which day was the number of puffs sold four times as many as the number of puffs sold on Wednesday? Give your answer in this format. (Eg Mon)
(a)
Number of puffs sold on Monday = 200
Number of puffs sold on Tuesday = 110
Number of puffs sold on Wednesday = 50
Number of puffs sold on Thursday = 100
Number of puffs sold on Friday = 80
Number of puffs sold on Saturday = 10
Number of puffs sold on Sunday = 180
Number of more puffs sold on Sunday than on Tuesday
= 180 - 110
= 70
(b)
Number of puffs sold on Wednesday = 50
Number of puffs sold in a day to be four times as many as the number of puffs sold on Wednesday
