I. Homework review
In 1996, the sales showed a general downward trend. British shoppers spent about 9% on Monday. Then the spending rose considerably on Tuesday and increased slightly to about 14% on Wednesday followed by a small drop on Thursday. It shot up again on Friday and peaked at approximately 22% on Saturday before collapsing at below 5% on Sunday.
In contrast, there was a general upward trend in the spending at all retailers in Britain in 2000. Although the spending started at about 7% on Monday, a noticeable lower volume than in 1996, it grew sharply on Tuesday to about 12%. Since then, there was a steady increase until Friday. On Friday, it reached the peak at about 19% while the sales afterwards decreased gradually to about 18%, well up that in 1996.
