Answer:
750 billion
Step-by-step explanation:
The computation of the net investment is shown below:
= Stock of capital on December 31, 2009 - Stock of capital on January 1, 2009
= $11,750 billion - $11,000 billion
= $750 billion
We simply take the difference between the ending balance of capital stock and the beginning balance of capital stock to compute the net investment level.
