Calculating the Total Price for 400 Widgets: Understanding Expressions

When faced with a scenario involving multiple widgets and a desired quantity, understanding the right expression is crucial for calculating the total price. This article will guide you through the process, outlining the key elements and providing a clear solution.

The Problem: Finding the Total Price

Let's assume you're buying widgets, and you need to know the total cost for purchasing 400 of them. You have the following information:

• Cost per widget: This is the price of a single widget. Let's represent this with the variable "c".
• Quantity: This is the number of widgets you want to buy (400 in this case).

The Goal: Find an expression that represents the total price for purchasing 400 widgets.

Solution: Using Multiplication

The simplest way to find the total price is to multiply the cost per widget by the quantity:

Total Price = Cost per widget * Quantity

Total Price = c * 400

Therefore, the expression "c * 400" represents the total price for 400 widgets.

Example: Putting it into Practice

Let's say the cost per widget "c" is $2.50. Using our expression, the total price would be:

Total Price = c * 400 = $2.50 * 400 = $1000

In this case, the total price for 400 widgets is $1000.

Key Takeaways

• The expression "c * 400" allows us to calculate the total price of any number of widgets, simply by substituting the cost per widget ("c") into the equation.
• This formula emphasizes the importance of understanding the relationship between unit price, quantity, and total cost.
• By using a simple expression, we can streamline calculations and avoid confusion.

Understanding the fundamental concepts of mathematical expressions is essential when dealing with quantities and pricing. This knowledge empowers you to efficiently calculate total costs in various scenarios, making it easier to manage budgets and plan purchases.
