Answer:
a. Commission
Explanation:
The commission payment system is based on an employee's output, mostly sales achieved. The commission is usually a percentage of the total sales per stipulated time, say weekly, biweekly, or monthly. In the commission-based payment, the more output an employee has, the more money they earn.
The scenario in the case is commission based. For every $100 worth of sales, the payment is $15. The more the sales, the higher the earnings.
