Suppose an economy starts the year with $100 million in capital, and during the course of a year, it adds $20 million of gross investment. Economists estimate that the depreciation rate for this economy is 9% per year. Required:
a. Calculate depreciation and net investment for this economy.
b. Calculate the value of net exports.

Correct word for question b. "Now calculate the amount of next year's beginning capital stock for this economy"

a. Begins the year with $100 million in capital. Depreciation rate is 9% per year

Depreciation = 9% * $100 million

Depreciation = 0.09 * $100 million\

Depreciation = $9 million

Gross investment = $20 million

Net investment = Gross investment - Depreciation

Net investment = $20 million - $9 million

Net investment = $11 million

b. Next year begining capital stock = Capital stock at the begining of previous year + Net investment

Next year begining capital stock = $100 million  + $11 million

Next year begining capital stock = $111 million

all of them make sense but, i would have to say ask someone who has been there/or lives there, and/or read recent newspapers from that city.

hope this !
