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

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

(a)
Number of croissants sold on Monday = 150
Number of croissants sold on Tuesday = 20
Number of croissants sold on Wednesday = 100
Number of croissants sold on Thursday = 60
Number of croissants sold on Friday = 50
Number of croissants sold on Saturday = 10
Number of croissants sold on Sunday = 240

Number of more croissants sold on Wednesday than on Friday
= 100 - 50
= 50

Number of croissants sold on Thursday = 60

Number of croissants sold in a day to be four times as many as the number of croissants sold on Thursday
= 4 x 60
