Actually forget it, Uncle Kadyo correctly proves that the answer is correct with his formula.
I was just wondering how to solve it if you don't have the value of x (or more accurately of p[rice], which in this case p=x). I don't know the answer, but it gets into some more complex math, I think. For instance, if the values were much more complex than simply $1+1/2x=p.

And I went ahead and took the liberty of sending a billion points over to Bringer for his correct answer myself.
What also are points good for than sending them around?
Maybe I'll go make a donation to the Point Giver while I'm at it.

let x = cost
1+1/2 x = x
1 = x -1/2 x
1 = 1/2 x
1/2 x = 1
2[1/2 x = 1]2
x = 2

As uncle kadyo has already demonstrated the answer is 2.
However the way the question is worded is deliberately confusing and counter-intuitive.Last edited by deliveryman; 12-23-2012, 02:57 AM.

But let me try. If half the cost plus one is equal to the cost, then half the cost is one. Ergo, the cost is 2.
