Answer:
a) increased nominal GDP by $20,000, but left real GDP unchanged.
Step-by-step explanation:
Gross domestic product is the sum of all final goods and services produced in an economy within a given period which is usually a year.
Nominal GDP is GDP calculated using current year prices.
Real GDP is GDP calculated using base year prices.
Nominal GDP = 1000 × $12 = $12,000
Nominal GDP increased by $12,000 but real GDP remained unchanged because the same amount of pizzas was produced both years.
