Introduction

In this article, we will explore the concept of representing the value of coins in mathematical expressions. Specifically, we will examine the value of 5 nickels and x dimes. Understanding how to represent the value of coins in mathematical expressions is essential in various fields, including finance, economics, and mathematics.

The Value of Coins

Before we dive into the mathematical representation of the value of coins, let's first understand the value of each coin. A nickel is worth $0.05, and a dime is worth $0.10.

Representing the Value of 5 Nickels

To represent the value of 5 nickels, we can multiply the value of one nickel by 5. This can be expressed as:

5 * 0.05 = 0.25

So, the value of 5 nickels is $0.25.

Representing the Value of x Dimes

To represent the value of x dimes, we can multiply the value of one dime by x. This can be expressed as:

0.10x

Representing the Value of 5 Nickels and x Dimes

Now that we have represented the value of 5 nickels and x dimes separately, we can combine them to represent the total value. To do this, we can add the value of 5 nickels and the value of x dimes. This can be expressed as:

0.25 + 0.10x

However, we can simplify this expression by combining the constant terms. This can be expressed as:

0.10x + 0.25

Evaluating the Options

Now that we have represented the value of 5 nickels and x dimes, let's evaluate the options provided:

A. $5(0.05) + 0.10x$ B. $0.10x + 5$ C. $5x + 10x$

Option A

Option A is $5(0.05) + 0.10x$ . This expression is equivalent to:

0.25 + 0.10x

This is the same expression we derived earlier, so option A is correct.

Option B

Option B is $0.10x + 5$ . This expression is equivalent to:

0.10x + 5

This is not the same expression we derived earlier, so option B is incorrect.

Option C

Option C is $5x + 10x$ . This expression is equivalent to:

15x

This is not the same expression we derived earlier, so option C is incorrect.

Conclusion

In conclusion, the correct expression that represents the value of 5 nickels and x dimes is:

0.10x + 0.25
