Question

1. from 259 hours to 274 hours %

Explanation:

Step1: Find the change in hours

To find the change, subtract the original value from the new value. So, \( 274 - 259 = 15 \) hours.

Step2: Calculate the percentage change

The formula for percentage change is \( \frac{\text{Change}}{\text{Original}} \times 100\% \). Here, the original value is 259, and the change is 15. So, \( \frac{15}{259} \times 100\% \approx 5.79\% \) (rounded to two decimal places).

Answer:

Approximately \( 5.79\% \) (or more precisely, \( \frac{1500}{259}\% \approx 5.79\% \))
