In the economy of Ukzten in 2010, consumption was $6000, exports were $1000, GDP was $10,000, government purchases were $2000, and imports were $600. What was Ukzten's investment in 2010?

I = $1,600

Explanation:

We have to clear Investment from the GDP formula:

GDP = Consumption (C) + Investment (I) + Government expenditure (G) + Net exports (exports-imports)

I=GDP-G-C - (X-M)

The problem gives this information:

GDP: $10,000

G: $2,000

C: $6,000

X: $1,000

M: $600

I = $10,000-$2,000-$6,000 - ($1,000-$600)

Investment in 2010=$1,600
