2.98 / 8 = ?

To determine the lower unit price per battery between the two options, we need to calculate the price per battery for each option.
Option 1: One 10-pack + one free battery for $5.49
Total batteries in Option 1 = 10 + 1 = 11
Price per battery in Option 1 = Total cost ÷ Total batteries
= $5.49 ÷ 11
= $0.499 per battery (rounded to the nearest cent)
Option 2: Two 4-packs for $2.98
Total batteries in Option 2 = 2 × 4 = 8
Price per battery in Option 2 = Total cost ÷ Total batteries
= $2.98 ÷ 8
= $0.3735 per battery (rounded to the nearest cent)
Now we compare the price per battery for both options.
Option 1: $0.499 per battery
Option 2: $0.3735 per battery
Therefore, Option 2, which offers two 4-packs for $2.98, has the lower unit price per battery.
