Final answer:
To determine which is a better deal, we need to compare the price per ounce for each brand of toothpaste. Brand B is a better deal as it has a lower price per ounce compared to Brand A.
Step-by-step explanation:
To determine which is a better deal, we need to compare the price per ounce for each brand of toothpaste.
For Brand A, the price per ounce is calculated by dividing the total cost ($5.22) by the number of ounces (17.4), which gives us $0.30 per ounce.
For Brand B, the price per ounce is calculated by dividing the total cost ($6.65) by the number of ounces (26.6), which gives us $0.25 per ounce.
Therefore, Brand B is a better deal as it has a lower price per ounce compared to Brand A.
