Final answer:
To calculate the commission, we apply a 5% commission to the first $5,000 in sales to get $250, and a 7.5% commission to the remaining $3,000 in sales to get $225. The total commission is $475.
Step-by-step explanation:
The subject is a word problem in mathematics related to the application of percentages and calculating commission. To solve the problem, we need to split the total sales into two parts: sales up to $5,000 and the sales exceeding $5,000. Then we apply the different commission rates to each part.
First, the salesperson earns a 5% commission on the first $5,000 of sales:
Next, the salesperson earns a 7.5% commission on the remaining $3,000 of sales (since $8,000 total sales - $5,000 threshold = $3,000):
Now, we add both amounts to determine the total commission:
Therefore, the salesperson's total commission for the month is $475.
