Understanding the Relationship Between Textbooks and Pages

When dealing with algebraic equations, it's essential to understand the relationship between variables and how they interact with each other. In this scenario, we're given a specific situation involving textbooks and their total number of pages. We'll explore how to represent the total number of pages, denoted as ${$ y $}$, in terms of the number of textbooks, denoted as ${$ x $}$.

The Given Information

We're told that four of the same textbooks contain a total of 848 pages. This information can be represented as an equation, where the total number of pages is equal to the number of textbooks multiplied by the number of pages per textbook. Since we're dealing with the same textbooks, we can assume that each textbook has the same number of pages.

Representing the Total Number of Pages

Let's denote the number of pages per textbook as ${$ p $}$. We can then represent the total number of pages as the product of the number of textbooks and the number of pages per textbook: ${$ y = xp $}$. However, we're not given the value of ${$ p $}$, and we're asked to represent the total number of pages in terms of the number of textbooks.

Simplifying the Equation

Since we know that four textbooks contain a total of 848 pages, we can set up an equation to represent this situation: ${$ 4p = 848 $}$. Solving for ${$ p $}$, we get ${$ p = 212 $}$. Now that we have the value of ${$ p $}$, we can substitute it into the equation representing the total number of pages: ${$ y = xp $}$.

Substituting the Value of ${$ p $}$

Substituting ${$ p = 212 $}$ into the equation, we get: ${$ y = x(212) $}$. This equation represents the total number of pages in terms of the number of textbooks.

Comparing the Options

Now that we have the equation representing the total number of pages, let's compare it with the given options:

A. ${$ 4x = 848 $}$ B. ${$ y = 4x + 848 $}$

Option A represents the equation ${$ 4p = 848 $}$, which we used to solve for ${$ p $}$. However, this equation does not represent the total number of pages in terms of the number of textbooks.

Option B represents the equation ${$ y = 4x + 848 $}$. This equation is incorrect because it adds 848 to the product of ${$ x $}$ and ${$ 4 $}$, rather than multiplying ${$ x $}$ by the number of pages per textbook.

The Correct Equation

The correct equation representing the total number of pages is: ${$ y = 212x $}$. This equation represents the total number of pages in terms of the number of textbooks, where each textbook has 212 pages.

Conclusion

In conclusion, when dealing with algebraic equations, it's essential to understand the relationship between variables and how they interact with each other. By representing the total number of pages in terms of the number of textbooks, we can create an equation that accurately models the situation. In this scenario, the correct equation representing the total number of pages is ${$ y = 212x $}$.
Frequently Asked Questions About Textbooks and Pages

In the previous article, we explored the relationship between textbooks and their total number of pages. We also discussed how to represent the total number of pages in terms of the number of textbooks. In this article, we'll answer some frequently asked questions about textbooks and pages.

Q: What is the relationship between the number of textbooks and the total number of pages?

A: The relationship between the number of textbooks and the total number of pages is represented by the equation ${$ y = xp $}$, where ${$ y $}$ is the total number of pages, ${$ x $}$ is the number of textbooks, and ${$ p $}$ is the number of pages per textbook.

Q: How do I find the total number of pages if I know the number of textbooks and the number of pages per textbook?

A: To find the total number of pages, you can multiply the number of textbooks by the number of pages per textbook: ${$ y = xp $}$.

Q: What if I don't know the number of pages per textbook?

A: If you don't know the number of pages per textbook, you can use the equation ${$ 4p = 848 $}$ to solve for ${$ p $}$. Once you have the value of ${$ p $}$, you can substitute it into the equation ${$ y = xp $}$ to find the total number of pages.

Q: Can I use the equation ${$ 4x = 848 $}$ to find the total number of pages?

A: No, you cannot use the equation ${$ 4x = 848 $}$ to find the total number of pages. This equation represents the equation ${$ 4p = 848 $}$, which is used to solve for ${$ p $}$. To find the total number of pages, you need to use the equation ${$ y = xp $}$.

Q: What if I have a different number of textbooks than 4?

A: If you have a different number of textbooks than 4, you can use the equation ${$ y = xp $}$ to find the total number of pages. Simply substitute the number of textbooks you have into the equation, and multiply it by the number of pages per textbook.

Q: Can I use the equation ${$ y = 4x + 848 $}$ to find the total number of pages?

A: No, you cannot use the equation ${$ y = 4x + 848 $}$ to find the total number of pages. This equation is incorrect because it adds 848 to the product of ${$ x $}$ and ${$ 4 $}$, rather than multiplying ${$ x $}$ by the number of pages per textbook.

Q: What is the correct equation to use to find the total number of pages?

A: The correct equation to use to find the total number of pages is ${$ y = xp $}$, where ${$ y $}$ is the total number of pages, ${$ x $}$ is the number of textbooks, and ${$ p $}$ is the number of pages per textbook.

Conclusion

In conclusion, understanding the relationship between textbooks and their total number of pages is essential for solving problems involving algebraic equations. By using the correct equation and substituting the given values, you can find the total number of pages. Remember to use the equation ${$ y = xp $}$ to find the total number of pages, and avoid using incorrect equations like ${$ 4x = 848 $}$ or ${$ y = 4x + 848 $}$.
