Answer:
Part A: 204 pages
Part B: 232 pages. 28 pages more.
Step-by-step explanation:
Eliza reads of her book on Monday by pages, where r is the total number of pages in the book.
On Tuesday and Wednesday combined, she reads three times as much as she reads on Monday i.e. pages.
So, combining Monday, Tuesday and Wednesday she reads number of pages.
Part A: If Eliza's book has a total of 357 pages then combining Monday, Tuesday and Wednesday she reads pages.
Part B: If Renee Reads the same fraction of a different book over the same period of time as Eliza, then if Renee's book has a total of 406 pages then combining Monday, Tuesday and Wednesday she reads a total of pages.
She reads (232 - 204) = 28 more pages than Eliza. (Answer)
