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

Number of sandwiches sold on Monday = 10
Number of sandwiches sold on Tuesday = 60
Number of sandwiches sold on Wednesday = 130
Number of sandwiches sold on Thursday = 40
Number of sandwiches sold on Friday = 90
Number of sandwiches sold on Saturday = 180
Number of sandwiches sold on Sunday = 160
Number of more sandwiches sold on Wednesday than on Friday
= 130 - 90
= 40

Number of sandwiches sold in a day to be four times as many as the number of sandwiches sold on Thursday
= 4 x 40
