(1) What is the percent of change from 24 to 30 ?

To find the percent of change from 24 to 30, we can follow these steps: 1. **Calculate the difference** between the new value and the old value. 2. **Divide the difference** by the absolute value of the old value. 3. **Multiply by 100** to convert it to a percentage. Let's denote: - Old value \( O = 24 \) - New value \( N = 30 \) Now, we can calculate the percent of change using the formula: \[ \text{Percent of Change} = \left( \frac{N - O}{|O|} \right) \times 100 \] Now, let's perform the calculations step by step: 1. Calculate the difference: \[ N - O = 30 - 24 = 6 \] 2. Divide by the old value: \[ \frac{6}{24} = 0.25 \] 3. Multiply by 100 to get the percentage: \[ 0.25 \times 100 = 25\% \] Thus, the percent of change from 24 to 30 is \( 25\% \).
