Ron paid $14 for a book and 4 pens. The price of each pen was 5/8 the price of the book.
How much did Ron pay for the book?
~~~~~~~~~~~~~ 

Let x = the price for the book, in dollars.

Then the proce for each pen is %285%2F8%29x.


The total cost equation is


    x + 4%2A%285%2F8%29x = 14.


Simplify and solve 


    x + %285%2F2%29x = 14

    2x + 5x = 28

      7x    = 28

       x    = 28/7 = 4  dollars.    ANSWER

Solved.
