Answer:
Both Mark and Steve will be paid the same amount.
Explanation:
According to a skill-based plan, each skill level is paid equally regardless of the job the employee is performing and his seniority. Here, although Mark is a better performer than Steve, and Steve is senior to Mark, but both are designated at the same job level. Therefore, as the company follows the skills-based plan that is based on establishing single flat rates for each skill level, both Mark and Steve will be paid the same amount.
