If the total amount of money in quarters and dimes is 28.80, how many quarters and how many dimes are in the box
~~~~~~~~~~~~~~~~~~ 

There are x dimes and 6x quarters.

Write the total cents equation

    10x + 25*6x = 2880  cents.



Simplify and find x

    10x + 150x = 1880

       160x = 2880

          x = 2880/160 = 18.



ANSWER.  18 dimes and 6*18 = 108 quarters.


CHECK.   18*10 + 108*25 = 2880  cents, total.   ! correct !

Solved.
