What is the prime reason that Jenny's discretionary income is more volatile than her salary? A. Her cost of living is affected by high inflation in the neighborhood
B. Her tax rate remains 30%

D. Her discretionary income and salary are equally volatile

c. Her mortgage payments and necessities are fixed
