You can put this solution on YOUR website! A coin Bank contains nickels, dimes, and quarters totaling 51 coins. The value of the coins is $6. Ir there are 4 more nickels than dimes , Find how many of each is the bank
------
Quantity: n + d + q = 51 coins
Value::: 5n +10d+25q = 600
Quantity: n - d = 4
------------------------
Solve the system by any method to get:
n = 21
d = 17
q = 13
