We have the following information:
• Brand A: 48 ounces for $1.39
• Brand B: 32 ounces for $0.89
And we need to find which of them has the lowest price per ounce.
So, to find the price per ounce of each brand, we need to divide the price by the total of ounces. We obtain:
Then, since 0.028 < 0.029, we see that:
Brand B has the lowest price per ounce.
