To calculate the commission as a percent of total monthly sales, use the following formula:
\[ \text{Commission Percentage} = \left( \frac{\text{Commission}}{\text{Total Sales}} \right) \times 100 \]
Given:
- Commission = $1,953
- Total Sales = $65,100
Now, substitute the values into the formula:
\[ \text{Commission Percentage} = \left( \frac{1,953}{65,100} \right) \times 100 \]
Calculating the fraction:
\[ \frac{1,953}{65,100} \approx 0.0300 \]
Now multiply by 100 to get the percentage:
\[ 0.0300 \times 100 \approx 3.00 \]
Thus, the salesman's commission as a percent of his total monthly sales is approximately:
\[ \boxed{3.00} % \]
