Answer:
Eliza reads a total of 204 pages in the three days combined.
Step-by-step explanation:
From the given information, we are being told that:
Eliza reads [tex]\dfrac{1}{7}[/tex] of her book on Monday.
On Tuesday and Wednesday combined, she reads thrice as much as she read on Monday.
Let assume that; Tuesday = T and Wednesday = W
Then;
[tex]T + w = 3 ( \dfrac{1}{7})[/tex]
The expression to determine the total number of pages is given as:
[tex]\large \dfrac{1}{7}r+3\left(\dfrac{1}{7}r\right)[/tex]
where;
r = total number of pages in the book.
Assuming that Eliza book contains a total of 357 pages. How many pages does she read in the three days combined together.
i.e.
r = 357
Then;
[tex]\implies \large \dfrac{1}{7}(357)+3\left(\dfrac{1}{7}(357)\right)[/tex]
[tex]\implies 51+3(51))[/tex]
[tex]\implies 51+153[/tex]
= 204 pages
Thus, Eliza reads a total of 204 pages in the three days combined.
