Eliza reads 1··7of her book on Monday. On Tuesday and Wednesday combined, she reads three times as much as she reads on Monday. The expression 1··7r 1 3 1 1··7r 2 can be used to determine the number of pages Eliza reads on Monday, Tuesday, and Wednesday combined. The variable r represents the total number of pages in the book. Part A Eliza’s book has a total of 357 pages. How many pages does Eliza read on Monday, Tuesday, and Wednesday combined? A 306 B 204 C 153 D 51

Respuesta :

The expression :

[tex]\frac{1}{7}r+3(\frac{1}{7}r)[/tex]

gives the number of pages Eliza read in those three days. If r=357, then we have that:

[tex]\frac{1}{7}(357)+3(\frac{1}{7}\cdot357)=51+153=204[/tex]

She read 204 pages on those days. Therefore, the answer is B.
