Final answer:
The population of the country in 2003 was 270.4 million.
Step-by-step explanation:
The exponential model A = 270.4 e⁰.⁰¹⁶ᵗ represents the population, A, of a country in millions, t years after 2003.
To determine the population of the country in 2003, we need to substitute 0 for t in the formula:
A = 270.4 e⁰.⁰¹⁶(0)
Since any number raised to the power of 0 is equal to 1, the equation simplifies to:
A = 270.4 * 1
A = 270.4 million
Therefore, the population of the country in 2003 was 270.4 million.
