Consider the open economy IS/LM model with the following functions:

C = 0.5(Y ?T), I = 1500 ? 250r, NX = 1000 ? 250e, L(Y, r) = 0.5Y ? 500r (money demand), CF = 500?250r.

Taxes, government purchases, the money supply, and price level are T = 1000, G = 1500, M = 1000, and P = 1.

Calculate the equilibrium values for GDP Y , the interest rate r, consumption C, investment I, net capital outflow CF, net exports NX, and the exchange rate e.

I am very confused because I keep getting different answers. Below is the possible answers I have got.

Y = 3250, r = 0.1, C = 1250, I = 1250, CF = 250, NX = 0, and e = 1.

or

Y = 5000, r = 0.2 , C = 2500, I = 1250, CF = 250, NX = 750, and e = 1.5.

or

e Y = 4500, r = 1, C = 1750, I = 750, CF = 250, NX = 500, and e = 2.

or all three of those could be wrong, so if you could please help me find the correct solution, that would be greatly appreciated it.
