Answer:
C+$64
Explanation:
The GDP measures the market value of all good and services produced in an economy (country or region) in a specific period of time. It is calculated by this formula:
GDP= Consumption (C)+ Investment (I)+ Government expenditure ()+ Net exports (exports-imports)
A lump-sum tax at all levels of GDP means that no matter what GDP value is, the tax will be the same amount. If the tax is collected by the government then the GDP will increase because the government expenditure is income ( most of them are taxes) minus expenses ( public investment in education, health, etc)
GDP= C+$34+$30+0
After tax, the equilibrium level of GDP will be C+$64
