Final answer:
The percentage decrease in staff is approximately 24.56%.
Step-by-step explanation:
To find the percentage decrease in staff, you need to calculate the difference between the initial number of employees and the final number of employees, and then divide that difference by the initial number of employees. This will give you the fraction of the decrease. To convert this fraction to a percentage, multiply it by 100. In this case:
Initial number of employees = 57
Final number ofemployees = 43
Difference = 57 - 43 = 14
Percentage decrease = (14 / 57) * 100 ≈ 24.56%
Therefore, the percentage decrease in staff is approximately 24.56%.
