eimsori [14]

Given:

Reese read twice as many pages Saturday than she read Sunday.

She read a total of 78 pages over the weekend.

To find:

The number of pages she read on Sunday.

Solution:

Reese read twice as many pages Saturday than she read Sunday. So, the number of pager she read on Saturday is 2x.

Total number of page she read over the weekend is:

$Total=x+2x$

$Total=3x$

She read a total of 78 pages over the weekend.

$3x=78$

$x=\dfrac{78}{3}$

$x=26$

Therefore, Reese read 26 pages on Sunday.
