Understanding the Impact of Algebraic Expressions in Real-Life Scenarios: A Simple Example with Pen Costs
In today's world, understanding basic mathematical concepts can be incredibly useful in everyday life. One such concept is the use of algebraic expressions, which can model real-life situations effectively. This article will explore a simple problem involving the cost of pens and how its solution can be used to determine the amount Vikas would receive back from the shopkeeper.
The Problem: Vikas's Pen Purchase
Vikas, a student or an office worker in need of stationary, decided to buy three pens, each costing x rupees. To further understand this scenario, let's break down the problem and explore its solution step by step.
Step 1: Calculate the Total Cost of the Pens
The first step in the process is to determine the total cost of the pens. Since each pen costs x rupees and Vikas purchased three of them, we can express the total cost as:
Total Cost of Pens 3 * x
Step 2: Calculate the Change from 100 Rupees
Next, we need to calculate the amount Vikas will get back from the shopkeeper after paying 100 rupees for the pens. The change can be found by subtracting the total cost of the pens from the amount Vikas gave the shopkeeper:
Change 100 - Total Cost of Pens
Substituting the total cost of the pens from Step 1, we get:
Change 100 - 3x
This expression tells us how much change Vikas will receive after his purchase.
