Calculate Gross National Product (GNP) and Net National Product (NNP) using the expenditure approach.

The formula for GNP using the expenditure approach is:

$$\text{GNP} = \text{Private Consumption Expenditure (C)} + \text{Gross Capital Formation (I)} + \text{Government Final Consumption Expenditure (G)} + (\text{Exports (X)} - \text{Imports (M)}) + \text{Net Factor Income from Abroad (NFIA)}$$

From the given data:

• Private consumption expenditure (C) = 186.1
• Gross capital formation (I) = 63.2
• Government final consumption expenditure (G) = 58.7
• Export of goods and services (X) = 15.0
• Import of goods and services (M) = 17.2
• Net factor income from Abroad (NFIA) = 1.3

$$\text{GNP} = 186.1 + 63.2 + 58.7 + (15.0 - 17.2) + 1.3$$ $$\text{GNP} = 186.1 + 63.2 + 58.7 - 2.2 + 1.3$$ $$\text{GNP} = 307.1$$

The Gross National Product is $\boxed{\text{307.1}}$.

The formula for NNP is:

$$\text{NNP} = \text{GNP} - \text{Consumption of Fixed Capital (Depreciation)}$$

From the given data:

• GNP = 307.1 (calculated in part a)
• Consumption of fixed capital (Depreciation) = 10.5

$$\text{NNP} = 307.1 - 10.5$$ $$\text{NNP} = 296.6$$

The Net National Product is $\boxed{\text{296.6}}$.

The formula for National Income (at factor cost) from NNP (at market prices) is:

$$\text{National Income} = \text{NNP} - \text{Indirect Business Taxes} + \text{Subsidies}$$

From the given data:

• NNP = 296.6 (calculated in part b)
• Indirect business taxes = 14.5
• Subsidies = 12.4

$$\text{National Income} = 296.6 - 14.5 + 12.4$$ $$\text{National Income} = 282.1 + 12.4$$ $$\text{National Income} = 294.5$$

The National Income is $\boxed{\text{294.5}}$.
