If C = 500, b = 0.75, and Y = 500, we can correctly conclude that

a. Autonomous Consumption = 0 b. Investment = 500

c. APC = 1 d. APS = 0.25

If imports are fixed, taxes equal zero, and the multiplier is given as 10, we can correctly estimate that

a. MPC = 0.10 b. MPS = 0.01

c. APS = 0.01 d. MPS = 0.10
