Answer:
The Real GDP Growth Rate = 26.15%
Real Interest Rate = 6%
Step-by-step explanation:
GDP = Consumption Expenditure + Government Purchases + Investment Expenditure + Net exports ( Exports - Imports)
Consumption Expenditure = Plastic bags + Bread
Consumption Expenditure = $1200 + $500
Consumption Expenditure = $1700
Government Spending = Bread = $300
Investment Expenditure = Final Bread made by bread company + Machines Purchased
Investment Expenditure = $100 + $500
Investment Expenditure = $600
Exports = Wheat Exported = $180
Imports = Imported Peanut Butter by Consumer + Imported Peanut Butter by Government
Imports = $80 + $90
Imports = $170
Net Exports = Exports - Imports
Net Exports = $180 - $170
Net Exports = $10
Total GDP = 1700 + 300 + 600 + 10
Total GDP = $2610
Nominal GDP in 2015 = Price * Quantity
Nominal GDP in 2015 = $2 * 15 + $3.50 * 10
Nominal GDP in 2015 = $30 + $35
Nominal GDP in 2015 = $65
Nominal GDP 2016 = $2.50 * 20 + $4 * 12
Nominal GDP 2016 = $50 + $48
Nominal GDP 2016 = $98
Real GDP 2015 = Nominal GDP 2015 = $65 . This is because 2015 is base year.
Real GDP 2016 = $2 * 20 + $3.50 * 12
Real GDP 2016 = $40 + $42
Real GDP 2016 = $82
The Real GDP Growth Rate = (Real GDP 2016 - Real GDP 2015) / Real GDP 2015 * 100
The Real GDP Growth Rate = (82 - 65) / 65 * 100
The Real GDP Growth Rate = 17/65 * 100
The Real GDP Growth Rate = 0.2615385 * 100
The Real GDP Growth Rate = 26.15%
b. Nominal interest Rate = 10%
Inflation Rate = 4%
Real Interest Rate = Nominal Interest Rate - Inflation Rate
Real Interest Rate = 10% - 4%
Real Interest Rate = 6%
