part a

from 74 hours to 85 hours.
answer:
%
part b
state if it is an increase or a decrease.
answer:

Explanation:

Step1: Calculate the change amount

The original value is 74 hours, and the new value is 85 hours. The change amount is \( 85 - 74 = 11 \) hours.

Step2: Use the percent - change formula

The formula for percent change is \( \text{Percent Change}=\frac{\text{New Value}-\text{Original Value}}{\text{Original Value}}\times100\% \). Substitute the values: \( \frac{85 - 74}{74}\times100\%=\frac{11}{74}\times100\% \)

Step3: Calculate the value

\( \frac{11}{74}\times100\%\approx14.86\% \), rounded to the nearest whole percent is \( 15\% \)

Step4: Determine increase or decrease

Since \( 85>74 \), it is an increase.

Answer:

Part A: 15
Part B: Increase
