The line graph shows the number of croissants sold in a week. 

1. How many more croissants were sold on Sunday than on Tuesday?
2. On which day was the number of croissants sold twice as many as the number of croissants sold on Wednesday? Give your answer in this format. (Eg Mon)

(a)
Number of croissants sold on Monday = 120
Number of croissants sold on Tuesday = 30
Number of croissants sold on Wednesday = 60
Number of croissants sold on Thursday = 180
Number of croissants sold on Friday = 80
Number of croissants sold on Saturday = 160
Number of croissants sold on Sunday = 190

Number of more croissants sold on Sunday than on Tuesday
= 190 - 30
= 160

(b)
Number of croissants sold on Wednesday = 60

Number of croissants sold in a day to be twice as many as the number of croissants sold on Wednesday
= 2 x 60
= 120

On Monday, the number of croissants sold was twice as many as the number of croissants sold on Wednesday.
