David = 20*7

David = 140 pages

After 7 days Audrey will have read 280 pages and David will have read 140 pages.

This question is based on the normal multiplication.Therefore, The number of pages  read after 7 days by Audrey will be 20 pages and David will be 140 pages.

Given:

Audrey reads 40 pages each day. David reads 20 pages each day.

According to the question,
