2. (a) Show your calculations.
• Given the consumption equation, C = 220 + .75Y. Calculate the numerical value of the break-even level of income, YB.
• Suppose that Investment spending of 420 is added (I = 420). Find Ye1.
• Then suppose that we find that ΔI = 40. Find Ye2.
• What is the multiplier effect of ΔI = 40? Explain and show this relationship.
3. (a) Calculate the numerical value of equilibrium level of income (Ye) if
C = 485 + .90Y, I = 560, G = 854, EX = 235, and IM = 340. Show your calculations.
