Peter read the same number of pages of his storybook each day. At the end of the

7th day, he was left with \( {1\over 4}\) of the total number of pages.  After another 2 days, he

was left with 10 pages.  How many pages are there in Peter's storybook?

Let the number of pages in his storybook ==P

Let the number of pages he read per day ==D

 

P  -  7D ==1/4P 

1/4P - 2D ==10, solve for P, D

 

P==280 pages in his book

D==30 pages per day he read
