Calculate GDP from the above figures:

GDP = Consumption + Gross Investment + Government Purchases + (Exports - Imports) Plugging in the values from the above list, we get:

GDP = 5000 + 1000 + 1500 + (500 - 100) GDP = 5000 + 1000 + 1500 + 400

GDP = 7900 billion

Calculate net investment from the above figures:

Net Investment = Gross Investment - Capital consumption allowance (Depreciation)

Net Investment = $1000 - $800

Net Investment =$200 billion

Calculate net domestic product (NDP) from the above figures:

NDP = GDP - Capital Consumption Allowance

Plugging in the values from the above list, we get:

NDP= 8400 - 800 NDP = 7600 billion

Calculate national income from the above figures:

National Income = GDP - Capital Consumption Allowance - Net Foreign Factor Income

Plugging in the values from the above list, we get:

National Income = 8400 - 800 - 4

National Income = 7596 billion

Calculate personal income from the above figures

Personal Income = National Income - Corporate Taxes - Social Security Taxes - Transfer Payments

Plugging in the values from the above list, we get:

Personal Income = 7596 - 100 - 800 - 1000

Personal Income = 6696 billion

Calculate disposable income from the above figures

Disposable Income = Personal Income - Personal Income Tax

Plugging in the values from the above list, we get:

Disposable Income = 6696 - 200

Disposable Income = 6496 billion
