Final answer:
The total earnings of a commissioned employee earning a 9.5% commission are calculated by multiplying 9.5% by their total_sales, which is represented by the expression 9.5 * total_sales.
Step-by-step explanation:
The correct expression that represents the total earnings of a commissioned employee earning a 9.5% commission rate on their sales is 9.5 * total_sales. This calculation is performed by multiplying the employee's commission rate (expressed as a decimal in calculations) by the total amount of sales they have generated. To calculate the total amount of a commissioned employee's earnings, you take the total sales and multiply it by their commission rate. For example, if the employee sells $1,000 worth of goods, their earnings would be calculated as $1,000 * 0.095 (9.5% expressed as a decimal), which equals $95.00.
