Can you show it by graph and explain the outcome of such a phenomenon? 10. Consider an economy described as follows: Y=C+/+G C=100 +0.75(Y-T) . 1=500-50r G=125 T= 100 -Where Y is GDP, C is consumption, I is investment, G is government expenditure, T is taxes and r is the interest rate. -If Y is 2000, what would be the interest rate? -Suppose the monetary authorities want to set interest rate at 4%. What would happen to Y
