Introduction

As the new school year approaches, students like Jess are preparing their school supplies. In this scenario, Jess purchased folders, spiral ring notebooks, and boxes of pencils. To understand the total cost of her purchase, we need to create an equation that represents the total amount she spent. In this article, we will explore the different equations that can be used to represent Jess's purchase.

The Cost of Folders and Notebooks

Jess purchased 5 folders for $\$0.89$ each and 4 spiral ring notebooks for $\$1.29$ each. To find the total cost of these items, we can multiply the number of each item by its respective price and then add the two amounts together.

\text{Cost of folders} = 5 \times \$0.89 = \$4.45
\text{Cost of notebooks} = 4 \times \$1.29 = \$5.16
\text{Total cost of folders and notebooks} = \$4.45 + \$5.16 = \$9.61

The Cost of Pencils

Jess also purchased $p$ boxes of pencils for $\$2.29$ each. To find the total cost of the pencils, we can multiply the number of boxes by the price of each box.

\text{Cost of pencils} = p \times \$2.29 = \$2.29p

The Total Cost of Jess's Purchase

To find the total cost of Jess's purchase, we need to add the cost of the folders and notebooks to the cost of the pencils.

\text{Total cost} = \text{Cost of folders and notebooks} + \text{Cost of pencils}
= \$9.61 + \$2.29p

Which Equation Can Be Used to Represent Jess's Purchase?

Based on the calculations above, we can see that the equation that represents Jess's purchase is:

\text{Total cost} = \$9.61 + \$2.29p

This equation takes into account the cost of the folders and notebooks, as well as the cost of the pencils.

Conclusion

In conclusion, the equation that can be used to represent Jess's purchase is $\text{Total cost} = \$9.61 + \$2.29p$ . This equation represents the total cost of Jess's purchase, including the cost of the folders, notebooks, and pencils.

Recommendations

When creating an equation to represent a real-world scenario, make sure to take into account all the relevant factors.
Use variables to represent unknown values, such as the number of boxes of pencils.
Use mathematical operations, such as multiplication and addition, to calculate the total cost.

Appendix

The following is a list of the equations used in this article:

$\text{Cost of folders} = 5 \times \$0.89 = \$4.45$
$\text{Cost of notebooks} = 4 \times \$1.29 = \$5.16$
$\text{Total cost of folders and notebooks} = \$4.45 + \$5.16 = \$9.61$
$\text{Cost of pencils} = p \times \$2.29 = \$2.29p$
$\text{Total cost} = \text{Cost of folders and notebooks} + \text{Cost of pencils} = \$9.61 + \$2.29p$
Jess's School Supplies Purchase: Q&A =====================================

Introduction

In our previous article, we explored the equation that represents Jess's purchase of school supplies. In this article, we will answer some frequently asked questions about Jess's purchase.

Q: What is the total cost of Jess's purchase?

A: The total cost of Jess's purchase is represented by the equation $\text{Total cost} = \$9.61 + \$2.29p$ , where $p$ is the number of boxes of pencils.

Q: How much did Jess spend on folders?

A: Jess spent $\$4.45$ on folders, which is the cost of 5 folders at $\$0.89$ each.

Q: How much did Jess spend on notebooks?

A: Jess spent $\$5.16$ on notebooks, which is the cost of 4 notebooks at $\$1.29$ each.

Q: What is the cost of one box of pencils?

A: The cost of one box of pencils is $\$2.29$ .

Q: How much will Jess spend on pencils if she buys 3 boxes?

A: If Jess buys 3 boxes of pencils, she will spend $3 \times \$2.29 = \$6.87$ on pencils.

Q: What is the total cost of Jess's purchase if she buys 3 boxes of pencils?

A: The total cost of Jess's purchase if she buys 3 boxes of pencils is $\$9.61 + \$6.87 = \$16.48$ .

Q: Can I use this equation to calculate the total cost of my own purchase?

A: Yes, you can use this equation to calculate the total cost of your own purchase. Simply substitute the number of folders, notebooks, and boxes of pencils you purchased into the equation.

Q: What if I don't know the number of boxes of pencils I purchased?

A: If you don't know the number of boxes of pencils you purchased, you can use the equation to represent the total cost as a function of the number of boxes of pencils. For example, if you know that the total cost is $\$16.48$ and you want to find the number of boxes of pencils, you can set up the equation $\$9.61 + \$2.29p = \$16.48$ and solve for $p$ .

Q: Can I use this equation to calculate the cost of other items?

A: No, this equation is specific to Jess's purchase and cannot be used to calculate the cost of other items. However, you can use the same principles to create an equation that represents the cost of your own purchase.
