Answer:
To calculate the percent decrease in staff, we need to find the difference between the original number of employees and the new number of employees, and then divide that difference by the original number of employees. Finally, we can multiply the result by 100 to get the percent decrease.
The difference between the original number of employees (61) and the new number of employees (9) is:
61 - 9 = 52
Dividing 52 by the original number of employees (61) gives:
52/61 ≈ 0.8525
Multiplying 0.8525 by 100 gives:
0.8525 × 100 ≈ 85.25
Therefore, the percent decrease in staff is approximately 85.25%. Rounded to the nearest tenth, the answer is 85.3%.
