Consider an economy in which the consumption, investment and production functions are as follows.

C = 9 + 0.7(Y T)

I = 25 2r

F(K, L) = K^(1/2) L^(1/2)

The capital and labor supply are equal to 100 each, G = 20 and T = 20. Compute the equilibrium values of output, overall labor income, consumption, public savings, national savings, investment, and the interest rate.
