You can put this solution on YOUR website! Coins in a store's register total $12.50. The register only has nickels, dimes, and quarters. There are twice as many dimes as nickels. There are also twice as many quarters as dimes. How many dimes are there?
------------
Let # of nickels be "x".
Then # of dimes is "2x".
And # of quarters is "4x"
-----------------------------
Value Equation: 5x + 10(2x) + 25(4x) = 1250 cents
5x + 20x + 100x = 1250
125x = 1250
x = 10 (# of nickels)
2x = 20 (# of dimes(
4x = 40 (# of quarters)
