The correct answer to the question is "Commission."
Explanation:
1. **Hourly Paid**: This option refers to receiving payment based on the number of hours worked, without any additional compensation related to sales or performance.
2. **Free Labor**: This term implies working without receiving any payment or compensation, which is not the case in the context of the question.
3. **Salary**: Salary is a fixed amount of money paid to an employee regularly, typically on a monthly or annual basis, regardless of sales performance.
4. **Commission**: When you earn a percentage of what you sell in addition to an hourly wage, it is known as earning a commission. This payment structure is common in sales roles where individuals receive a base hourly wage along with a commission based on the sales they generate.
In summary, the correct term for getting paid an hourly wage and a percentage of what you sell is "Commission."
