Answer:
The statement "The 8-count pack of AA batteries has a lower unit price of $0.77 per battery" is true.
Here's an explanation:
To determine the unit price, we divide the total cost of the package by the number of batteries it contains.
For the 8-count pack:
Unit price = Total cost / Number of batteries
Unit price = $6.16 / 8
Unit price = $0.77 per battery
For the 20-count pack:
Unit price = Total cost / Number of batteries
Unit price = $15.60 / 20
Unit price = $0.78 per battery
Since the unit price of the 8-count pack is $0.77 per battery and the unit price of the 20-count pack is $0.78 per battery, the statement that the 8-count pack of AA batteries has a lower unit price of $0.77 per battery is true.
