The line graph shows the number of sandwiches sold in a week.
- How many more sandwiches were sold on Sunday than on Tuesday?
- On which day was the number of sandwiches sold four times as many as the number of sandwiches sold on Wednesday? Give your answer in this format. (Eg Mon)
(a)
Number of sandwiches sold on Monday = 200
Number of sandwiches sold on Tuesday = 80
Number of sandwiches sold on Wednesday = 50
Number of sandwiches sold on Thursday = 70
Number of sandwiches sold on Friday = 120
Number of sandwiches sold on Saturday = 180
Number of sandwiches sold on Sunday = 110
Number of more sandwiches sold on Sunday than on Tuesday
= 110 - 80
= 30
(b)
Number of sandwiches sold on Wednesday = 50
Number of sandwiches sold in a day to be four times as many as the number of sandwiches sold on Wednesday
= 4 x 50
= 200
On Monday, the number of sandwiches sold was four times as many as the number of sandwiches sold on Wednesday.
