✓

Answer

Average Propensity to Consume (APC) is the ratio of total consumption to total income, i.e., $\text{APC}=\frac{\text{C}}{\text{Y}}.$Whereas Average Propensity to Save (APS) is the ratio of total savings to total income, i.e., $\text{APS}=\frac{\text{S}}{\text{Y}}.$
The relationship between APC and APS is as follows:
APC + APS = 1
APC = 1 - APS APS = 1 - APC
