Final answer:
Discretionary income is more important than disposable income for businesses that sell expensive watches, second homes, and financial services.
Step-by-step explanation:
For businesses that sell expensive watches, second homes, and financial services, discretionary income is more important than disposable income.
Discretionary income refers to the money a person has left after paying for necessities like rent, bills, and groceries. It represents the amount of money that can be spent on luxury items like expensive watches or second homes.
On the other hand, disposable income refers to the income after taxes. It is the amount of money available for spending after taxes have been deducted.
