The line graph shows the number of sandwiches sold in a week.
- How many more sandwiches were sold on Saturday than on Thursday?
- On which day was the number of sandwiches sold four times as many as the number of sandwiches sold on Monday? Give your answer in this format. (Eg Mon)

Number of sandwiches sold on Monday = 10
Number of sandwiches sold on Tuesday = 120
Number of sandwiches sold on Wednesday = 200
Number of sandwiches sold on Thursday = 150
Number of sandwiches sold on Friday = 40
Number of sandwiches sold on Saturday = 190
Number of sandwiches sold on Sunday = 110
Number of more sandwiches sold on Saturday than on Thursday
= 190 - 150
= 40

Number of sandwiches sold in a day to be four times as many as the number of sandwiches sold on Monday
= 4 x 10
