Answer:$ 50 million
Step-by-step explanation:
We know GDP is calculated as the sum of consumption spending(C),Investment spending(I),Government spending(G) and net export(X).
Here
- Consumption spending

- investment spending

- Government spending

- $5 million worth tables are sold abroad
- no tables are imported.
At the end of year
GDP=C+I+G+X-M
GDP=10+20+10+5-0=$45 million
and the remaining 50,000 table worth of $5 million in inventory goes to the investment made by private sector
thus value of GDP is $ 50 million.
