thanks for the help

Suppose that an economy is characterized by the following behavioral equations: C = 0.65Yp + 630 - 25r 1005 100+1-1 / - 900 - 30r E -2.91 G - 900 * = 24,700 T - 690 * =3% IM = 0.15Y - 2100 + 700E IT- 3% EX -0.1 Y* - 750E r=r+1 IT = 2% F = 1% Y* is foreign output. NX - EX - IM equilibrium equation: Y= C+/+G+NX E is the nominal exchange rate. I'D = Y- T is the foreign nominal interest rate. Inflation and interest rates are in percent units (e.g., enter 2, not 0.02). Exogenous changes are permanent. Suppose autonomous expenditure falls by 600. 1. Calculate the change in output
