To represent Lelah's situation using an inequality, we need to consider her budget and the expenses.
- She has a total budget of $135.
- She spends $35.25 on shoes.
- The price of each shirt is $18.25, and she wants to buy \( s \) shirts.
After buying the shoes, the amount of money left to spend on shirts is \( 135 - 35.25 \). She then spends \( 18.25 \cdot s \) for the shirts.
Thus, we can formulate the inequality as follows:
\[ \text{Amount spent on shirts} \leq \text{remaining budget} \]
This gives us the inequality:
\[ 18.25s + 35.25 \leq 135 \]
Hence, the correct representation of Lelah's buying situation is:
18.25s + 35.25 ≤ 135
