Understanding Unit Prices and Making Smart Purchases

When it comes to making informed decisions in the marketplace, understanding unit prices is crucial. Unit prices, also known as price per unit, refer to the cost of a product per unit of measurement, such as per ounce, pound, or liter. In this article, we will explore how to calculate unit prices and use them to make smart purchasing decisions.

Calculating Unit Prices

To calculate the unit price of a product, we need to divide the total price by the number of units. For example, if a product costs $1.50 for a 12-ounce can, the unit price would be:

$1.50 ÷ 12 ounces = $0.125 per ounce

Four Packages of the Same Product: Which One is the Cheapest?

Let's consider four packages of the same product with different unit prices:

(a) 15 cents an ounce
(b) 2 ounces for 31 cents
(c) 1 ounce for 17 cents
(d) 1/2 ounce for 8 cents

To determine which package is the cheapest, we need to calculate the unit price for each package.

Package (a) - 15 cents an ounce

The unit price for package (a) is already given as 15 cents per ounce.

Package (b) - 2 ounces for 31 cents

To calculate the unit price for package (b), we need to divide the total price by the number of units:

31 cents ÷ 2 ounces = 15.5 cents per ounce

Package (c) - 1 ounce for 17 cents

The unit price for package (c) is already given as 17 cents per ounce.

Package (d) - 1/2 ounce for 8 cents

To calculate the unit price for package (d), we need to divide the total price by the number of units:

8 cents ÷ 0.5 ounces = 16 cents per ounce

Comparing Unit Prices

Now that we have calculated the unit prices for each package, let's compare them:

Package (a) - 15 cents per ounce
Package (b) - 15.5 cents per ounce
Package (c) - 17 cents per ounce
Package (d) - 16 cents per ounce

Based on the calculations, package (a) is the cheapest option, followed by package (d), package (b), and package (c).
