Question 900905
Biff has a collection of pennies, nickels, dimes and quarters worth $2.73 altogether. He has twice as many nickels as dimes, one more nickel than quarters, and two more than twice as many pennies as nickels. How many of each kind of coin does Biff have?
----------------------------
Value Eq:: p + 5n + 10d + 25q = 273 cents
Quantity Eqs:: 
n = 2d ; so d = n/2
n = q+1 ; so q = n -1
n = 2p+2 ; so p = (n-2)/2
-------
Substitute for d,q, and p ; solve for n.
-------------------
(n-2)/2 + 5n + 10(n/2) + 25(n-1) = 273
-----
Solve for "n" and will be able to solve for p,n, and Q.
