The value for this economy's real GDP in Year 2 is $3,030 billion.
GDP is calculated using the formula: GDP = C + I + G + (X - M), where C represents consumption spending, I represents business investment, G represents government purchases, X represents export sales, and M represents imports.
In Year 2, the values given are C = $2,000 billion, I = $50 billion, G = $1,000 billion, X = $20 billion, and M = $40 billion.
Substituting these values into the formula, we have: GDP = $2,000 billion + $50 billion + $1,000 billion + ($20 billion - $40 billion).
Simplifying the equation, we get: GDP = $3,030 billion.
