An Engaging Math Puzzle: How Many Erasers Did You Buy?

Math puzzles and riddles can be challenging yet rewarding, offering a mental workout and a chance to flex your problem-solving skills. Here’s a simple yet intriguing puzzle that playfully challenges your logical reasoning and algebraic skills. Let's dive into the puzzle game!

The Puzzle

Imagine you bought a magazine for $2, and then purchased some erasers, with each costing $4. After these purchases, you ended up spending a total of $14. Now, the question is: how many erasers did you buy?

Breaking Down the Problem

To tackle this puzzle, let's start by defining the variables and setting up an algebraic equation. We'll let x represent the number of erasers you bought.

The cost of the magazine is $2, and the cost of each eraser is $4. Therefore, for x erasers, the total cost of the erasers would be $4x. Adding the $2 spent on the magazine, the total cost can be expressed as:

$2 4x $14

Step-by-Step Solution

First, we need to isolate the variable term on one side of the equation. We'll subtract 2 from both sides to do this: $2 4x - 2 $14 - 2 4x $12 Next, divide both sides by 4 to solve for x: 4x / 4 $12 / 4 x 3

Hence, you bought 3 erasers.

Understanding the Solution

The above algebraic steps clearly show how to set up the equation and solve for the unknown quantity. This puzzle not only tests your basic math skills but also your attention to detail and logical reasoning. You need to follow a systematic method to arrive at the correct answer.
