Let's assume the number of pages Susan read yesterday is x.
According to the problem, Susan read 8 pages fewer than 13 of the pages she read yesterday, so she read 13x-8 pages today.
Since Susan read 17 pages today, we can set up the equation 13x-8 = 17.
Adding 8 to both sides, we get 13x = 25.
Finally, dividing both sides by 13, we find x = 25/13 = 1.92.
So, Susan read 1.92 pages yesterday.
Susan read 17 pages today. That is 8 pages fewer than 13 of the pages she read yesterday. How many pages did she read yesterday
