To determine which option has the lower unit price, we can calculate the unit price for each option:
For one bag of pretzels: Unit price = Total cost / Number of bags = 3 per bag
For five bags of pretzels: Unit price = Total cost / Number of bags = 2 per bag
Therefore, the option with five bags of pretzels has the lower unit price, at $2 per bag.
