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 = 240
Number of sandwiches sold on Tuesday = 140
Number of sandwiches sold on Wednesday = 60
Number of sandwiches sold on Thursday = 40
Number of sandwiches sold on Friday = 190
Number of sandwiches sold on Saturday = 160
Number of sandwiches sold on Sunday = 200
Number of more sandwiches sold on Sunday than on Tuesday
= 200 - 140
= 60
(b)
Number of sandwiches sold on Wednesday = 60
Number of sandwiches sold in a day to be four times as many as the number of sandwiches sold on Wednesday
= 4 x 60
= 240
On Monday, the number of sandwiches sold was four times as many as the number of sandwiches sold on Wednesday.
Answer(s): (a) 60; (b) Mon
