Solution

Solution Steps

Step 1: Calculate the Absolute Change

The absolute change in the number of students from 2014 to 2015 is calculated by subtracting the number of students in 2015 from the number of students in 2014: $\text{Absolute Change} = \text{students}_{2015} - \text{students}_{2014} = 450 - 500 = -50$

Step 2: Calculate the Relative Change

The relative change is calculated by dividing the absolute change by the initial number of students (in 2014) and then converting it to a percentage: $\text{Relative Change} = \left( \frac{\text{Absolute Change}}{\text{students}_{2014}} \right) \times 100 = \left( \frac{-50}{500} \right) \times 100 = -10.0\%$

Step 3: Determine the Correct Statement

Based on the calculations:

The absolute change is $-50$ students.
The relative change is $-10.0\%$ .

Among the given options, the correct statement is: d.) The absolute change is $-50$ students, and the relative change indicates a decrease of $10\%$ .
