Introduction

In this article, we will delve into the world of mathematics and explore the concept of algebraic equations and bar diagrams. We will use a real-life scenario to demonstrate how these mathematical tools can be used to represent and solve problems. Kala, a cheese enthusiast, bought two types of cheese at a deli: American cheese and Swiss cheese. We will use a bar diagram and an equation to represent her purchase and analyze the total number of pounds of cheese she bought.

The Bar Diagram

A bar diagram is a graphical representation of data that can be used to visualize and compare different values. In this case, the bar diagram represents the total number of pounds of cheese Kala bought.

	American Cheese	Swiss Cheese
Weight (pounds)	0.50	1.25

The Equation

An equation is a mathematical statement that expresses the equality of two expressions. In this case, the equation represents the total number of pounds of cheese Kala bought.

p = 0.50 + 1.25

Solving the Equation

To solve the equation, we need to add the two values on the right-hand side.

p = 0.50 + 1.25

p = 1.75

Interpretation

The equation $p = 0.50 + 1.25$ represents the total number of pounds of cheese Kala bought. By solving the equation, we found that the total number of pounds of cheese Kala bought is 1.75 pounds.

Conclusion

In this article, we used a bar diagram and an equation to represent Kala's cheese purchase. We solved the equation to find the total number of pounds of cheese Kala bought. This example demonstrates how mathematical tools can be used to represent and solve real-life problems.
