You can put this solution on YOUR website! Jason emptied his piggy bank and counted exactly $10 in nickels, dimes and quarters There were twice as many dimes as nickels. There were twice as many quarters as dimes. How many nickels did he have?--------------------
-------
5n + 10d + 25q = 1000 cents
d = 2n
q = 2d
--------
Substitute for "n" and "q" and solve for "d"::
5(d/2) + 10d + 25(2d) = 1000
5d + 20d + 100d = 2000
125d = 2000
d = 16 (# of dimes)
--------------------------
n = d/2 = 8 (# of nickels)
------
q = 2d = 32 (# of quarters)
