Answer:
The APC before change in disposable income was 0.75.
Explanation:
The average propensity to consume shows the part of income that is is consumed. It can be calculated as the ratio of total disposable income to total consumption.
The disposable income is given as $200 billion, the consumption level is $150 billion, the savings level is $50 billion.
Average propensity to consume is
= [tex]\frac{Consumption}{Disposable\ income}[/tex]
= [tex]\frac{\$ 150\ billion}{\$ 200\ billion}[/tex]
= 0.75
So, the average propensity to consume is 0.75.
