To calculate the salesman's total salary for the week, we start with his fixed weekly salary and then add the commission based on his sales.
-
Fixed Salary: The weekly salary is $800.
-
Sales: His total sales for the week were $750.
-
Sales over $500: He earns a 5% commission on sales over $500. The amount of sales over $500 is calculated as follows:
\[ 750 - 500 = 250 \]
-
Commission Calculation: Now we calculate the commission on the $250:
\[ \text{Commission} = 5% \text{ of } 250 = 0.05 \times 250 = 12.5 \]
-
Total Salary: Finally, we add the commission to the fixed salary:
\[ \text{Total Salary} = 800 + 12.5 = 812.5 \]
So, the salesman's total salary for the week is $812.50.
