Answer: b. $8,518.9 billion.
Step-by-step explanation:
Nominal GDP is calculated with current prices which means that the effects of inflation are present.
Real GDP removes this effect by basing the GDP calculation on the prices of a previous period:
Real GDP = Nominal GDP * 100/ Price level
= 8,800 * 100/ 103.3
= $8,518.877
= $8,518.9 billion
