To calculate the commission earned by the salesperson, you can multiply the total sales amount by the commission rate.
Here's the calculation:
\[ \text{Commission} = \text{Total Sales} \times \text{Commission Rate} \]
Given:
- Total Sales = $238,000
- Commission Rate = 5% = 0.05 (as a decimal)
Calculating the commission:
\[ \text{Commission} = 238,000 \times 0.05 = 11,900 \]
The salesperson earned $11,900 in commission last month.
