Question 4757: I know Fred bought 100 marbles for $1.00. I also know red marbles are 2 cents, shooter marbles are 3 cents and multicolored marbles are 2 for 1 cent. What kind of marbles and how many of each would Fred have? Answer by longjonsilver(2297) (Show Source):
You can put this solution on YOUR website! Let r = number of red marbles
Let s = number of shooters
Let m = number of multicoloured marbles.
We know that r+s+m=100 marbles.
We also know that 2r + 3s + 0.5m = 100 --> all prices in cents
I can see no other piece of information relating the marbles, so we have 3 unknowns but just 2 equations - you cannot solve this. You need one more equation at least.
