To set up the inequality for Omar's situation, we start by defining the terms involved:
- Let \( p \) be the number of pairs of socks Omar buys.
- Each pair of socks costs $4, so the total cost for \( p \) pairs of socks is \( 4p \).
- Omar has a coupon for $5 off his total purchase.
- With the coupon, the total cost for the socks becomes \( 4p - 5 \).
- Omar has a gift card worth $25, so the total amount he can spend (after using the coupon) should not exceed $25.
Setting up the inequality, we have:
\[ 4p - 5 \leq 25 \]
This inequality represents the condition that Omar's total cost (after applying the coupon) must be less than or equal to the amount on his gift card.
