Answer:
To find the unit cost of each brand, you can calculate the cost per ounce.
For RinSit:
\[ \text{Unit cost for RinSit} = \frac{\text{Cost of RinSit}}{\text{Volume of RinSit}} \]
\[ \text{Unit cost for RinSit} = \frac{1.29}{22} \]
For the store brand:
\[ \text{Unit cost for store brand} = \frac{\text{Cost of store brand}}{\text{Volume of store brand}} \]
\[ \text{Unit cost for store brand} = \frac{1.19}{25} \]
Now you can compute these values to find the unit cost for each brand.
