Fiona's Savings Account: Understanding the Concept of Doubling the Original Amount

In mathematics, understanding the concept of doubling an original amount is a fundamental skill that can be applied to various real-world scenarios. In this article, we will explore how to represent the new balance in Fiona's savings account after she doubles the original amount, and we will also calculate the new balance when the original amount is $160.

Fiona starts with an original amount of $s$ in her savings account. She then doubles this amount, which means she adds the original amount to itself. To represent this new balance, we need to find an expression that represents the sum of the original amount and the doubled amount.

To represent the new balance, we can use the expression $2s$. This expression represents the sum of the original amount $s$ and the doubled amount $s$. In other words, when we double the original amount, we are essentially adding the original amount to itself, which results in a new balance of $2s$.

Now that we have the expression $2s$ to represent the new balance, we can calculate the new balance when the original amount is $160. To do this, we simply substitute $s = 160$ into the expression $2s$.

2s = 2(160)
= 320

Therefore, when the original amount is $160, the new balance in Fiona's savings account is $320.

In conclusion, the expression $2s$ represents the new balance in Fiona's savings account after she doubles the original amount. When the original amount is $160, the new balance is $320. This problem demonstrates the importance of understanding the concept of doubling an original amount and how it can be applied to real-world scenarios.

The concept of doubling an original amount has numerous real-world applications. For example, in finance, doubling an investment can result in significant returns. In business, doubling production can lead to increased revenue. In personal finance, doubling savings can help individuals achieve their financial goals.

When working with expressions like $2s$, it's essential to remember that the expression represents the sum of the original amount and the doubled amount. To calculate the new balance, simply substitute the original amount into the expression and perform the necessary calculations.

When working with expressions like $2s$, it's common to make mistakes. Some common mistakes include:

• Forgetting to double the original amount
• Not substituting the original amount into the expression
• Not performing the necessary calculations

To avoid these mistakes, make sure to carefully read and understand the problem, and take your time when working with expressions like $2s$.

To practice working with expressions like $2s$, try the following problems:

• If the original amount is $120, what is the new balance after doubling the amount?
• If the original amount is $180, what is the new balance after doubling the amount?

• If the original amount is $120, the new balance is $240.
• If the original amount is $180, the new balance is $360.
  Fiona's Savings Account: Q&A

In our previous article, we explored how to represent the new balance in Fiona's savings account after she doubles the original amount. We also calculated the new balance when the original amount is $160. In this article, we will answer some frequently asked questions related to the concept of doubling an original amount.

Q: What is the expression that represents the new balance in Fiona's savings account after she doubles the original amount?

A: The expression that represents the new balance is $2s$. This expression represents the sum of the original amount $s$ and the doubled amount $s$.

Q: How do I calculate the new balance when the original amount is $120?

A: To calculate the new balance, simply substitute $s = 120$ into the expression $2s$. This results in a new balance of $2(120) = 240$.

Q: What is the new balance in Fiona's savings account when the original amount is $180?

A: To calculate the new balance, simply substitute $s = 180$ into the expression $2s$. This results in a new balance of $2(180) = 360$.

Q: Can I use the expression $2s$ to represent the new balance when the original amount is a negative number?

A: Yes, you can use the expression $2s$ to represent the new balance when the original amount is a negative number. However, keep in mind that the new balance will also be a negative number.

Q: How do I represent the new balance when the original amount is a fraction?

A: To represent the new balance when the original amount is a fraction, simply substitute the fraction into the expression $2s$. For example, if the original amount is $\frac{1}{2}$, the new balance is $2(\frac{1}{2}) = 1$.

Q: Can I use the expression $2s$ to represent the new balance when the original amount is a decimal?

A: Yes, you can use the expression $2s$ to represent the new balance when the original amount is a decimal. Simply substitute the decimal into the expression $2s$. For example, if the original amount is $3.5$, the new balance is $2(3.5) = 7$.

Q: What is the new balance in Fiona's savings account when the original amount is $0?

A: When the original amount is $0, the new balance is also $0. This is because doubling $0$ results in $0$.

Q: Can I use the expression $2s$ to represent the new balance when the original amount is a variable?

A: Yes, you can use the expression $2s$ to represent the new balance when the original amount is a variable. Simply substitute the variable into the expression $2s$. For example, if the original amount is $x$, the new balance is $2x$.

In conclusion, the expression $2s$ represents the new balance in Fiona's savings account after she doubles the original amount. We have answered some frequently asked questions related to the concept of doubling an original amount, and we have provided examples of how to calculate the new balance in various scenarios.

To practice working with expressions like $2s$, try the following problems:

• If the original amount is $150, what is the new balance after doubling the amount?
• If the original amount is $200, what is the new balance after doubling the amount?
• If the original amount is $-50, what is the new balance after doubling the amount?

• If the original amount is $150, the new balance is $300.
• If the original amount is $200, the new balance is $400.
• If the original amount is $-50, the new balance is $-100.
