Answer:
C) 175.
Explanation:
Sure, here's a step-by-step solution:
Let's call the number of employees at the agency "x".
If 80% of the employees have more than 12 days of unused sick leave, that means 0.8 * x employees have more than 12 days of unused sick leave.
We know that 0.8 * x = 140, so we can solve for x by dividing both sides of the equation by 0.8:
x = 140 / 0.8
Simplifying, we get:
x = 175
So there are 175 employees who work at the agency, and the answer is C) 175.
