To find out how many caramel brownies Eve brought, we first need to determine how many of the 25 brownies were caramel.
Given that 72% of the brownies are caramel, we calculate the number of caramel brownies as follows:
\[ \text{Number of caramel brownies} = \text{Total brownies} \times \frac{\text{Percentage of caramel brownies}}{100} \]
\[ \text{Number of caramel brownies} = 25 \times \frac{72}{100} \]
\[ \text{Number of caramel brownies} = 25 \times 0.72 \]
\[ \text{Number of caramel brownies} = 18 \]
Therefore, Eve brought in 18 caramel brownies.
