1. If imports are $2 trillion, exports are $1.9 trillion, consumption is $3.8 trillion, investment is $700 billion, and government spending is $1.1 trillion, how much is GDP ?
2. If consumption is $2.5 trillion, investment is $900 billion, government spending is $700 billion, imports are $1.2 trillion and exports are $1.4 trillion, how much is GDP?
Example: If GDP rises from $6 trillion in 1994 to $8 trillion in 1999 and the GDP deflator in 1999 is 110, find real GDP in 1999 and find the percentage increase in real GDP between 1994 and 1999.
First, we are asked to find real GDP in 1999. To do this we divide the nominal GDP, which is $8 trillion ($8,000 billion), by the GDP deflator for 1999, which is 110. This then is multiplied by 100.
Real GDP in 1999 is $7,273 billion or $7.2 trillion. To find the percent change you must find the difference of real GDP between 1999 and 1994.
Change in GDP = 7,232 – 6,000 = 1,232
You then take this difference and divide it by GDP in the base year, 1994, which is 6,000. This gives the percent change between 1990 and 1994.
3. GDP rises from $4 trillion in 2010 to $7 trillion in 2013. The GDP deflator in 2013 is 120. Find real GDP in 2013. Find the percentage increase in GDP between 2010 and 2013.
4. GDP rises from $5.5 trillion in 2014, the base year, to $9.5 trillion in 2018. The GDP deflator in 2018 is 140. Find real GDP in 2018. Find the percentage increase in real GDP between 2014 and 2018.
Example: Find per capita GDP when population is 10 million and GDP is $45 million.
To find per capita GDP you must divide GDP by the population.
per capita GDP = GDP = $45,000,000,000 = $4,500
Population 10,000,000
5. Find per capita GDP when population is 100 million and GDP is $2 trillion.
6. Find per capita GDP when population is 300 million and GDP is $1.5 trillion.

- The Following Questions include graphs that I cannot upload if you can please help with visuals also, thank you. The following graph shows the consumption function (C) for a hypothetical private closed economy and a 45-degree line along which aggregate expenditure equals real GDP (AE=Y). Recall that a private closed economy does not have government and does not trade with the rest of the world (so G=0 and (X-M)=0). In a private closed economy, real GDP is equal to disposable income. At the current real interest rate, the level of investment in this economy is equal to $50 billion at each level of real GDP. Use the blue line (circle symbols) to plot this economy's initial aggregate expenditure line, (C + I). Then, use the black point (X symbol) to indicate this economy's initial equilibrium output. Dashed drop lines will automatically extend to both axes. (Hint: You can see two of the coordinates along the consumption function by mousing over the green triangles on the graph.)
