A jar contains a mixture of nickels and dimes worth a total of $4.75. There are three times as many nickels as dimes. How many dimes are there?
-------
Quantity Equation: n = 3d
Value Equation: 5n + 10d = 475 cents
-----
Substitute for "n" and solve for "d":
5*3d + 10d = 475
25d = 475
d = 19 (# of dimes)
Since n = 3d , n = 57 (# of nickels)
