Final answer:
The club made $6675 after expenses.
Step-by-step explanation:
To find the amount of money the club made after expenses, we first need to calculate the total cost of the hats they ordered. The cost of each hat is $5.15, and they ordered 500 hats. So, the total cost is $5.15 x 500 = $2575.
Next, we calculate the total revenue generated from selling all the hats. The selling price of each hat is $18.50, and they sold all 500 hats. So, the total revenue is $18.50 x 500 = $9250.
To find the amount of money the club made after expenses, we subtract the total cost from the total revenue: $9250 - $2575 = $6675.
Therefore, the expression that shows the amount of money the club made after expenses is $6675.
