Final answer:
To find the unit price, you divide the total cost of $8.39 by 12 kg, which results in a unit price of approximately $0.70 per kilogram, rounded to the nearest cent.
Step-by-step explanation:
To determine the unit price of an item, you divide the total cost of the item by the total number of units. For the given problem, the total cost is $8.39 for 12 kilograms (kg) of the item. The unit price is calculated by dividing the total cost by the number of kilograms.
Unit Price = Total Cost / Number of Kilograms
= $8.39 / 12 kg
When you perform the division, you find that the unit price is approximately $0.70 per kilogram.
Since we are asked to round to the nearest cent if necessary, the final unit price is $0.70/kg.
