Step 1 :The table shows data for real GDP in trillions of dollars for Habanero Island. The data for the years 2017 and 2018 are as follows: \[\begin{tabular}{|c|r|} \hline Year & real GDP (\$ trillions) \\ \hline 2017 & 18 \\ \hline 2018 & 18.5 \\ \hline \end{tabular}\]
Step 2 :The real GDP growth from 2017 to 2018 can be calculated using the formula: \[\text{GDP growth} = \frac{\text{GDP in 2018} - \text{GDP in 2017}}{\text{GDP in 2017}} \times 100\%\]
Step 3 :Substitute the given values into this formula: \[\text{GDP growth} = \frac{18.5 - 18}{18} \times 100\%\]
Step 4 :Simplify the expression to get the GDP growth: \[\text{GDP growth} = 2.7777777777777777\%\]
Step 5 :Round the result to two decimal places: \[\text{GDP growth} = 2.78\%\]
Step 6 :Final Answer: The real GDP growth from 2017 to 2018 is approximately \(\boxed{2.78\%}\).
