Answer:
1. Amount required to fund the plan = % of injured*Total employees* Annual salary
Amount required to fund the plan = 4%*200 people* $600
Amount required to fund the plan = $4800
2. Amount contributed by each employee = Amount required to fund the plan / Number of employees
Amount contributed by each employee = $4800/200
Amount contributed by each employee = $24
3. Percentage of salary = Amount contributed by each employee / Salary
Percentage of salary = 24/600
Percentage of salary = 0.04
Percentage of salary = 4%
