Final answer:
To calculate the unit price of the rice, divide the total cost of $26.87 by the weight of 9 kg to get the price per kilogram. The unit price then needs to be rounded to the nearest cent, resulting in $2.99 per kilogram.
Step-by-step explanation:
To find the unit price of the rice, you would divide the total cost of the bag by the total weight of the bag. The formula for calculating the unit price is:
Unit Price = Total Cost ÷ Total Weight
Using the numbers provided:
Unit Price = $26.87 ÷ 9 kg
To find the cost per kilogram, we follow these steps:
- Divide the total cost by the total weight: $26.87 ÷ 9 kg = $2.986666667 per kilogram.
- Round to the nearest cent: Since we need our answer in terms of cents, we convert our answer to cents and then round. $2.986666667 is the same as 298.6666667 cents. Rounding to the nearest cent, we get 299 cents per kilogram, or $2.99 per kilogram when converted back to dollars.
Therefore, the unit price of the rice is $2.99 per kilogram, rounded to the nearest cent.
