he found that he 2 more bundles of magazines than books. How many books did he buy?
~~~~~~~~~~~~~~

Let x be number of magazines;  then the number of books was  1.25x.


The number of bundles for books     is  .

The number of bundles for magazines is  .


The difference of bundles was 2, which gives you this equation


     -  = 2.


To solve it, multiply both sides by 60.  You will get


    10x - 7.5x = 120

       2.5x    = 120

          x    = 120/2.5 = 48.


So, there were 48 magazines and  48 * 1 1/4 = 60 books.


ANSWER.   60 books.

Solved.
