Answer:
First we need to find the increase in her disposable income by subtracting the old disposable income from the new disposable income.
Old Disposable income= 40,000
New disposable income = 50,000
Change in disposable income = 50,000-40,000= 10,000
Although her mpc is 0.8 we need to find out what proportion of her disposable income does she spend on consumption.
So her disposable income was 40,000 and consumption was 36,000
36,000/40,000= 0.9
This means that Jane spends 90% of her dispoasble income on consumption, so if her disposable income increase by 10,000 her increase in consumption was
0.9*10,000= 9,000
Increase in consumption = $9,000
