He Also Has A Coupon For $5$ Off His Entire Purchase. Omar Wants To Know How Many Pairs Of Socks He Can Buy.Let $p$ Be The Number Of Pairs Of Socks Omar Buys. Write An Inequality That Represents The Situation: $4p - 5 \leq
Introduction
In today's world of discounts and promotions, it's essential to understand how to calculate the value of a coupon or a discount. In this article, we will explore a scenario where Omar wants to buy pairs of socks using a coupon that offers a $5 discount on his entire purchase. We will write an inequality that represents the situation and provide a step-by-step solution to help Omar determine how many pairs of socks he can buy.
The Coupon Discount
Omar has a coupon for $5 off his entire purchase. This means that if he buys a certain number of pairs of socks, he will get a discount of $5 on the total price. Let's assume that the price of each pair of socks is $x. Then, the total price of p pairs of socks is $px.
Writing the Inequality
Since Omar has a coupon for $5 off his entire purchase, the total price of p pairs of socks will be reduced by $5. Therefore, the inequality that represents the situation is:
where is the total price of p pairs of socks, and is the maximum amount Omar is willing to spend.
Simplifying the Inequality
To simplify the inequality, we can add to both sides:
This means that the total price of p pairs of socks must be less than or equal to $25.
Finding the Maximum Number of Pairs
Now, we need to find the maximum number of pairs of socks Omar can buy. To do this, we can divide both sides of the inequality by :
This means that the maximum number of pairs of socks Omar can buy is .
Example
Let's say the price of each pair of socks is $5. Then, the maximum number of pairs Omar can buy is:
This means that Omar can buy at most 5 pairs of socks.
Conclusion
In this article, we wrote an inequality that represents the situation where Omar wants to buy pairs of socks using a coupon that offers a $5 discount on his entire purchase. We simplified the inequality and found the maximum number of pairs of socks Omar can buy. This example demonstrates how to use mathematical concepts to solve real-world problems.

Frequently Asked Questions: Understanding the Coupon Discount ================================================================
Q: What is the coupon discount?
A: The coupon discount is a $5 discount on Omar's entire purchase of pairs of socks.
Q: How do I write an inequality to represent the situation?
A: To write an inequality, you need to represent the total price of p pairs of socks, which is $px, and subtract the coupon discount of $5. The resulting inequality is:
Q: How do I simplify the inequality?
A: To simplify the inequality, you can add $5 to both sides:
This means that the total price of p pairs of socks must be less than or equal to $25.
Q: How do I find the maximum number of pairs of socks Omar can buy?
A: To find the maximum number of pairs of socks Omar can buy, you can divide both sides of the inequality by :
