The GDP deflator is calculated using the formula:
\[ \text{GDP Deflator} = \left( \frac{\text{Nominal GDP}}{\text{Real GDP}} \right) \times 100 \]
Given:
- Nominal GDP = $5,500
- Real GDP = $5,000
Substituting the values into the formula:
\[ \text{GDP Deflator} = \left( \frac{5500}{5000} \right) \times 100 \]
\[ \text{GDP Deflator} = \left( 1.1 \right) \times 100 \]
\[ \text{GDP Deflator} = 110 \]
Therefore, the GDP deflator is 110.
