Question: 1 / 400

What is the unit price of the better buy when comparing $211.85 for 620 batteries and $8.69 for 24 batteries?

0.25

0.34

To determine the better buy between the two options, we need to calculate the unit price for each purchase by dividing the total cost by the quantity of batteries.

For the first option, which costs $211.85 for 620 batteries:

Unit price = Total cost / Quantity = $211.85 / 620 ≈ $0.3414 (rounded to four decimal places)

For the second option, which costs $8.69 for 24 batteries:

Unit price = Total cost / Quantity = $8.69 / 24 ≈ $0.36125 (rounded to five decimal places)

Now, we compare the direct results. The calculated unit price for the first option is approximately $0.34, while for the second option, it is approximately $0.36125. Since $0.34 is lower than $0.36125, the first option provides a better value per battery.

Thus, the unit price of the better buy is approximately $0.34, which corresponds to the calculation done for the larger quantity of batteries at $211.85 for 620 batteries.
