Question 246743
A box of coins contains a total of 26:00 in nickels, dimes, and quarters. If there is the same number of nickels as dimes, but twice as many quarters as nickels, how many dimes are in the box?
----------------------------------------
Equations:
5n + 10d + 25q = 2600 cents
n = d
q = 2n
----------------

Substitute and solve for "n":
5n + 10n + 25(2n) = 2600
65n = 2600
n = 40 (# of nickels)
d = n = 40 (# of dimes)
