The correct answer is: B. less than $90 per hour
The single rate method is a method of paying employees in which all employees are paid the same rate, regardless of their job title or experience. This method is often used in businesses with a small number of employees or in businesses that want to keep their costs down.
In the case of the employees of division A, who work for 8000 hours for $90 per hour, the single rate method would result in a rate of less than $90 per hour for the employees of division B. This is because the employees of division B are not as experienced as the employees of division A, and they are not doing as much work.
The other options are incorrect because:
- Option A is incorrect because the single rate method does not guarantee that all employees will be paid the same rate.
- Option C is incorrect because the single rate method does not guarantee that all employees will be paid more than $90 per hour.
- Option D is incorrect because the single rate method is a valid method of paying employees.
