Final answer:
Using the formula for calculating GDP, which includes consumption, investment, government spending, and net exports, we found that net exports are 0. This does not match any of the options given, suggesting a potential error in the question.
Step-by-step explanation:
The GDP (Gross Domestic Product) can be calculated using the formula: Consumption + Investment + Government spending + (Exports – Imports) = C+I+G+(X–M). Given that GDP is 300; consumption is 200; investment is 80; government expenditure is 20, we can find the net exports by plugging these values into the formula and solving for (X – M).
GDP = C + I + G + (X – M)
300 = 200 + 80 + 20 + (X – M)
300 = 300 + (X – M)
X – M = 300 – 300
X – M = 0
Given the provided information, the correct answer is that the net exports must be 0, which is not one of the provided options (A) 100 (B) 80 (C) 60 (D) 40. This implies that there was a possible error in the options provided as none of them match the calculated value.
