Introduction

In this article, we will explore the concept of representing mathematical expressions to describe real-world scenarios. We will use the example of Ahmed, who doubles his savings and then deposits an additional hundred dollars. Our goal is to create an expression that represents the current amount in his savings account and the current value of his account.

Understanding the Problem

Let ${$ s $}$ represent the amount Ahmed originally had in savings. After doubling his savings, the new amount can be represented as ${$ 2s $}$. However, Ahmed does not stop there; he also deposits an additional hundred dollars. To represent this, we need to add the hundred dollars to the new amount.

Representing the Current Amount

To represent the current amount in Ahmed's savings account, we need to add the hundred dollars to the new amount after doubling his savings. This can be represented as:

${$ 2s + 100 $}$

This expression shows that Ahmed's current savings account balance is equal to twice the original amount plus an additional hundred dollars.

Representing the Current Value of the Account

The current value of Ahmed's account is also equal to the current amount in his savings account. Therefore, the expression for the current value of his account is the same as the expression for the current amount:

${$ 2s + 100 $}$

Conclusion

In this article, we have explored the concept of representing mathematical expressions to describe real-world scenarios. We have used the example of Ahmed, who doubles his savings and then deposits an additional hundred dollars. Our goal was to create an expression that represents the current amount in his savings account and the current value of his account. We have shown that the expression ${$ 2s + 100 $}$ represents both the current amount and the current value of Ahmed's account.

Example Use Cases

Doubling Savings: If Ahmed originally had ${$ 50 $}$ in savings, his new amount after doubling his savings would be ${$ 100 $}$. If he then deposits an additional hundred dollars, his current amount would be ${$ 200 $}$.
Depositing Additional Funds: If Ahmed originally had ${$ 20 $}$ in savings, his new amount after doubling his savings would be ${$ 40 $}$. If he then deposits an additional hundred dollars, his current amount would be ${$ 140 $}$.

Mathematical Representation

The mathematical representation of the current amount in Ahmed's savings account can be expressed as:

${$ 2s + 100 $}$

This expression shows that the current amount is equal to twice the original amount plus an additional hundred dollars.

Solving for the Original Amount

If we know the current amount in Ahmed's savings account, we can solve for the original amount. Let's say the current amount is ${$ 300 $}$. We can set up the equation:

${$ 2s + 100 = 300 $}$

Subtracting 100 from both sides gives us:

${$ 2s = 200 $}$

Dividing both sides by 2 gives us:

${$ s = 100 $}$

Therefore, the original amount in Ahmed's savings account was ${$ 100 $}$.

Conclusion

Q: What is the original amount in Ahmed's savings account?

A: The original amount in Ahmed's savings account is represented by the variable ${$ s $}$. This means that the value of ${$ s $}$ is unknown and can be any positive number.

Q: How much is Ahmed's new amount after doubling his savings?

A: Ahmed's new amount after doubling his savings is ${$ 2s $}$. This is twice the original amount in his savings account.

Q: How much is Ahmed's current amount after depositing an additional hundred dollars?

A: Ahmed's current amount after depositing an additional hundred dollars is ${$ 2s + 100 $}$. This is the sum of the new amount after doubling his savings and the additional hundred dollars.

Q: What is the current value of Ahmed's account?

A: The current value of Ahmed's account is the same as the current amount in his savings account, which is ${$ 2s + 100 $}$.

Q: How can I solve for the original amount if I know the current amount?

A: To solve for the original amount, you can set up the equation ${$ 2s + 100 = current\ amount $}$ and then solve for ${$ s $}$. For example, if the current amount is ${$ 300 $}$, you can set up the equation ${$ 2s + 100 = 300 $}$ and then solve for ${$ s $}$.

Q: What if I want to find the current amount if I know the original amount and the additional hundred dollars?

A: To find the current amount, you can use the expression ${$ 2s + 100 $}$ and substitute the value of ${$ s $}$ with the original amount. For example, if the original amount is ${$ 50 $}$ and the additional hundred dollars is ${$ 100 $}$, you can substitute ${$ s $}$ with ${$ 50 $}$ and get ${$ 2(50) + 100 = 200 $}$.

Q: Can I use this expression to represent other real-world scenarios?

A: Yes, you can use this expression to represent other real-world scenarios where an amount is doubled and then increased by a fixed amount. For example, you can use this expression to represent the cost of an item that is doubled in price and then increased by a sales tax.

Q: How can I apply this concept to my own life?

A: You can apply this concept to your own life by thinking about situations where an amount is doubled and then increased by a fixed amount. For example, you can think about the cost of a product that is doubled in price and then increased by a sales tax. You can also use this concept to calculate the total cost of a project that involves doubling an initial investment and then adding additional funds.

Q: What are some common applications of this concept?

A: Some common applications of this concept include:

Calculating the total cost of a project that involves doubling an initial investment and then adding additional funds.
Determining the current value of an investment that has been doubled and then increased by a fixed amount.
Calculating the cost of a product that is doubled in price and then increased by a sales tax.
Representing the current amount in a savings account that has been doubled and then increased by a fixed amount.
