Question 8 Real GDP in the economy is $7,900 Billion and the Marginal Propensity to Consume is 0.56. What will Real GDP in the economy be, in $ Billions, after a $10 Billion increase in Government Spending? (Round your FINAL answer to the nearest whole number/integer.) (BE VERY CAREFUL NOT TO ROUND "MIDDLE" CALCULATIONS. ONLY ROUND THE FINAL ANSWER.) (Do not enter a dollar sign, $. or the word "Billion", just the number.)
