Understanding Unit Price

Unit price is a crucial concept in mathematics, particularly in finance and economics. It represents the cost of a single unit of a product, usually expressed in terms of currency per unit of measurement. In this article, we will explore how to calculate the unit price of a product, using a 28-ounce jar of spaghetti sauce priced at $\$ 2.89$ as an example.

What is Unit Price?

Unit price is calculated by dividing the total cost of a product by its quantity. This can be expressed mathematically as:

Unit Price = Total Cost ÷ Quantity

Calculating Unit Price: A Step-by-Step Approach

To calculate the unit price of a 28-ounce jar of spaghetti sauce priced at $\$ 2.89$ , we need to follow these steps:

Identify the total cost and quantity: The total cost of the spaghetti sauce is $\$ 2.89$ , and its quantity is 28 ounces.
Divide the total cost by the quantity: To calculate the unit price, we need to divide the total cost by the quantity. This can be expressed mathematically as:

Unit Price = $\$ 2.89$ ÷ 28

Evaluating the Options

Now that we have a clear understanding of how to calculate the unit price, let's evaluate the given options:

Option a: $(\$ 2.89)(28)$

This option represents the product of the total cost and the quantity, which is not the correct way to calculate the unit price.

Option b: $\$ 2.89 - 28$

This option represents the difference between the total cost and the quantity, which is also not the correct way to calculate the unit price.

Option c: $\frac{28}{\$ 2.89}$

This option represents the division of the quantity by the total cost, which is the correct way to calculate the unit price.

Option d: $\frac{\$ 2.89}{28}$

This option represents the division of the total cost by the quantity, which is the correct way to calculate the unit price.

Conclusion

In conclusion, the correct way to calculate the unit price of a 28-ounce jar of spaghetti sauce priced at $\$ 2.89$ is by dividing the total cost by the quantity. This can be expressed mathematically as:

Unit Price = $\$ 2.89$ ÷ 28

The correct option is d. $\frac{\$ 2.89}{28}$ , which represents the division of the total cost by the quantity.

Final Answer

$The final answer is $\boxed{\frac{\$ 2.89}{28}}$.<br/> **Unit Price Calculations: Frequently Asked Questions**$
