Question 1000532
Janelle checks her coin supply and finds that she only has dimes quarters and pennies. she has the same number of pennies as dimes and half as many quarters. if she has ten coins altogether worth 94 cents how many of each kind of coins does she have? 
---------------
The following is a confusing statement:: "she has the same number of pennies as dimes and half as many quarters".
If it means what it seams to say, you have 4 equations and only 3 variables.
------------------- 
Equations:

p = d
q = p/2
p + d + q = 10
p + 10d+ 25q = 94
------------
Substituting with the top two equations you would get:
p + p + p/2 = 10
(5/2)p = 10
p = 4 (# of pennies)
----
Substituting the same 2 into the bottom equation you would get:
p + 10p + (25/2)p = 94
21.5p = 94
p = 4.37 (# of pennies)
------
Conclusion:: Confusion
