This nation's GDP is

$315 billion.

$324 billion.

$305 billion.

$367 billion.

Option C ($305 million) is the correct answer.

Explanation:

GDP = GNP - Net foreign factor income

GNP can be calculated by using the following formula

GNP (FC) = NNP (FC) + depreciation

NNP (FC) = 300, thus the depreciation is as follows:

Depreciation = Gross private domestic investment - Net private domestic investment

= 55 minus 40 = 15

Now, we can calculate GNP (FC) by substituing the values into the formula

GNP (FC) = 300 plus 15 = 315

Now, we can calculate GDP by by substituing the values into the formula.

GDP = 315 minus 10 = 305

Thus, the value of U. S. GDP is $305 billion

Therefore, the correct answer is option C
