Understanding the Problem: A Math Conundrum for Janelle and Her Cousins

When it comes to solving math problems, it's essential to break down the information and identify the key elements. In this scenario, Janelle and her twin cousins, Maria and Marquita, are planning to attend a 7:00 P.M. show. The problem at hand is to determine the total cost of the tickets. To solve this, we need to understand the cost of each ticket and how to calculate the total cost.

The Cost of Each Ticket

Let's assume that the cost of Janelle's ticket is $5, and the cost of each of her twin cousins' tickets is $8. We need to find the total cost of the three tickets.

Evaluating the Options

We have three different expressions to evaluate:

a. $$2($$5+$ $8)$ $ b. $$$$5+2($ $8)$ $ c. $$3($ $8)$ $

To determine the correct expression, let's analyze each option:

Option a: $$2($$5+$ $8)$ $

This expression involves multiplying the result of the sum of $5 and $8 by 2. First, we need to find the sum of $5 and $8, which is $13. Then, we multiply $13 by 2, resulting in a total cost of $26.

Option b: $$$$5+2($ $8)$ $

This expression involves adding $5 to the result of multiplying $8 by 2. First, we need to multiply $8 by 2, resulting in $16. Then, we add $5 to $16, resulting in a total cost of $21.

Option c: $$3($ $8)$ $

This expression involves multiplying $8 by 3, resulting in a total cost of $24.

Conclusion

Based on the analysis of each option, the correct expression to find the total cost of Janelle and her twin cousins' tickets is:

2(\$$5+\$$8)

This expression accurately represents the total cost of the three tickets, which is $26.

Why This Expression is Correct

This expression is correct because it takes into account the cost of all three tickets. The sum of $5 and $8 represents the cost of Janelle's ticket and one of her twin cousins' tickets. Multiplying this sum by 2 represents the cost of the third ticket, which is also $8. Therefore, the total cost of the three tickets is $26.

Real-World Applications

This type of problem is relevant in real-life situations, such as when planning a group outing or event. Understanding how to calculate the total cost of multiple items or services is essential for making informed decisions and avoiding financial surprises.

Tips for Solving Similar Problems

When faced with a problem like this, follow these steps:

Frequently Asked Questions: Understanding the Total Cost of Janelle and Her Cousins' Tickets

In our previous article, we explored the problem of finding the total cost of Janelle and her twin cousins' tickets to a 7:00 P.M. show. We analyzed three different expressions and determined that the correct expression is:

2(\$$5+\$$8)

However, we understand that you may still have questions about this problem. In this article, we'll address some of the most frequently asked questions and provide additional clarification.

Q: Why is the correct expression $$2($$5+$ $8)$ $ and not $$$$5+2($ $8)$ $ or $$3($ $8)$ $?

A: The correct expression is $$2($$5+$ $8)$ $ because it takes into account the cost of all three tickets. The sum of $5 and $8 represents the cost of Janelle's ticket and one of her twin cousins' tickets. Multiplying this sum by 2 represents the cost of the third ticket, which is also $8. This expression accurately represents the total cost of the three tickets.

Q: What if the cost of Janelle's ticket was $10 and the cost of each of her twin cousins' tickets was $8? How would we calculate the total cost?

A: If the cost of Janelle's ticket was $10 and the cost of each of her twin cousins' tickets was $8, we would use the same expression:

2(\$$10+\$$8)

First, we would find the sum of $10 and $8, which is $18. Then, we would multiply $18 by 2, resulting in a total cost of $36.

Q: Can we use the expression $$3($ $8)$ $ to find the total cost of Janelle and her twin cousins' tickets?

A: No, we cannot use the expression $$3($ $8)$ $ to find the total cost of Janelle and her twin cousins' tickets. This expression only takes into account the cost of two tickets, not three. To find the total cost of three tickets, we need to use an expression that takes into account the cost of all three tickets, such as $$2($$5+$ $8)$ $.

Q: How can we apply this concept to real-life situations?

A: This concept can be applied to real-life situations where you need to calculate the total cost of multiple items or services. For example, if you're planning a group outing or event, you may need to calculate the total cost of tickets, food, and other expenses. By understanding how to calculate the total cost of multiple items or services, you can make informed decisions and avoid financial surprises.

Q: What are some common mistakes to avoid when calculating the total cost of multiple items or services?

A: Some common mistakes to avoid when calculating the total cost of multiple items or services include:

Not taking into account the cost of all items or services
Using the wrong expression or formula
Not considering the order of operations
Not double-checking your calculations

By avoiding these common mistakes, you can ensure that you're getting an accurate calculation of the total cost.

Conclusion

We hope this article has helped to clarify any questions you may have had about finding the total cost of Janelle and her twin cousins' tickets. Remember to always take into account the cost of all items or services, use the correct expression or formula, and consider the order of operations to ensure that you're getting an accurate calculation of the total cost.
