You can put this solution on YOUR website! A boy has a bag of quarters and dimes that equal 60 coins also total $7.00 how many quarters does he have
-------------------
Let # of quarters be "x" ; value is 25x cents
---------
# of dimes is "60-x" ; value is 10(60-x) = 600-10x cents
------------
EQUATION:
value + value = 700 cents
25x + 600-10x = 700
15x = 100
x = 20/3
-------
Comment: x cannot be 20/3; it must be a whole number if
if is the number of quarters. Please check your data.
