Question

Find each unit price. Which is the better buy? Explain Electrical wire : $1.49 for 3 ft or $.69 for 18 in. Explain

Answer 1

To determine the better buy between two options of electrical wire, the unit price of each is calculated. The second option at $0.46 per foot is identified as the better buy compared to the first option at $0.4967 per foot.

Step-by-step explanation:

To determine which is the better buy for the electrical wire, we need to calculate the unit price for each option. The unit price is the cost per unit of measure, which in this case, is per foot.

First, let's calculate the unit price for the $1.49 for 3 ft option:

Unit price = Total price / Total feet
Unit price = $1.49 / 3 ft
Unit price = $0.4967 per foot (rounded to four decimal places)

Next, let's calculate the unit price for the $0.69 for 18 inches option. There are 12 inches in a foot, so 18 inches is 1.5 feet.

Unit price = Total price / Total feet
Unit price = $0.69 / 1.5 ft
Unit price = $0.46 per foot

Comparing the unit prices, the second option at $0.46 per foot is cheaper than the first option at $0.4967 per foot. Therefore, the $0.69 for 18 inches of electrical wire is the better buy.

Answer 2

here unit price = price / length

$1.49 / 3 = $0.50 / ft
$0.69 / 1.5 = $0.46 / ft
