Quizplus · Accepted Answer

The marginal propensity to save (MPS) is the complement of the marginal propensity to consume (MPC). Given the consumption function C = 7,250 + 0.8Y, the MPC is 0.8, indicating that for every additional unit of income, consumption increases by 0.8 units. Therefore, the MPS = 1 - MPC = 1 - 0.8 = 0.2.
