Final answer:
The unit price for the 4.07-pound bag of shrimp is $2.99 per pound and the unit price for the 5.11-pound bag is $2.93 per pound. The 5.11-pound bag is the better buy since it has a lower unit price.
Step-by-step explanation:
To calculate the unit price for each bag of shrimp, we divide the total cost by the weight of the bag in pounds.
For the 4.07-pound bag that cost $12.16, the unit price is calculated as follows:
Unit price for the 4.07-pound bag = $12.16 ÷ 4.07 pounds = $2.99 per pound (rounded to the nearest cent).
For the 5.11-pound bag that cost $14.99, the unit price is:
Unit price for the 5.11-pound bag = $14.99 ÷ 5.11 pounds = $2.93 per pound (rounded to the nearest cent).
To determine which bag is the better buy, we compare the unit prices.
Since the unit price for the 5.11-pound bag is lower, it is the better buy compared to the 4.07-pound bag.
