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

1. How many more muffins were sold on Saturday than on Thursday?
2. On which day was the number of muffins sold twice as many as the number of muffins sold on Monday? Give your answer in this format. (Eg Mon)

(a)
Number of muffins sold on Monday = 30
Number of muffins sold on Tuesday = 170

Number of muffins sold on Thursday = 90
Number of muffins sold on Friday = 60
Number of muffins sold on Saturday = 130
Number of muffins sold on Sunday = 200

Number of more muffins sold on Saturday than on Thursday
= 130 - 90
