A country's domestic supply of saving, domestic demand for saving for purposes of capital formation, and supply of net capital inflows are given by the following equations:

S= 1,380 + 2,000r

I= 2,000 4,000r

KI= -100 + 6,000r

Assuming that the market for saving and investment is in equilibrium, find the current values fornational saving, capital inflows, domestic investment, and the real interest rate.
