Final answer:
The correct inequality to represent how many pairs of socks Helena can buy while staying within her budget is 38 + 2.50n ≤ 50.
Step-by-step explanation:
In this question, Helena has at most $50 to spend on shoes and socks. The pair of shoes she likes costs $38. Socks are priced at $2.50 per pair.
To represent the inequality that shows how many pairs of socks Helena can buy while staying within her budget, we need to find the maximum number of pairs of socks she can purchase along with the shoes. Let's assume the number of pairs of socks is represented by 'n'.
The total amount spent on shoes and socks should be less than or equal to $50. So, the correct inequality would be:
38 + 2.50n ≤ 50
