3. Assume that a large open economy with a floating exchange rate is described in the short run by the equations:
C = 0.5(Y - T)
T = 1000
I = 1500 - 250r
G = 1100
NX = 1000 - 250e
M/P = 0.5Y - 500r
M = 1000, P = 1
CF = 500 - 250r

CF denotes net capital outflow, and NX denotes the net exports.
The short-run equilibrium values of Y=___, C =___, r =___, I =___, CF =___, e =___, and NX =___. If the government cuts T to 600, then the short-run equilibrium values of Y =___, C =___, r =___, I =___, CF =___, e =___, and NX =___. According to above results, when the government cuts taxes, the real interest rate will ___ and the exchange rate will ___.
