```You are purchasing skateboards and the salesperson offers you a $25 discount if you purchase 5 or more skateboards at $75 each. Write an expression to determine how much the skateboards would cost in total if you receive the discount and purchase more than 5 skateboards.

*
75s - 25
75s + 25
25s - 75
25s + 75

75s - 25

To write an expression to determine the total cost of skateboards if you receive the discount and purchase more than 5 skateboards, you can use the following formula:

Total cost = 75s - 25

In the formula above:
- s represents the number of skateboards you purchase.
- 75 is the price of each skateboard.
- 25 is the discount offered.

By multiplying the number of skateboards (s) by the price per skateboard (75) and subtracting the discount amount (25), you will get the total cost of the skateboards after the discount has been applied.

To determine the total cost of skateboards after receiving the discount, you would write the expression:

75s - 25

where "s" represents the number of skateboards purchased.
