To find the value of \( y \), which represents the total cost of the garlic powder, we can first calculate the total cost of the oregano and garlic powder.
-
Calculate the total cost of oregano:
- Oregano: 4 ounces at $4 per ounce \[ \text{Total cost of oregano} = 4 , \text{ounces} \times 4 , \text{dollars/ounce} = 16 , \text{dollars} \]
-
Calculate the total cost of garlic powder:
- Garlic Powder: 2 ounces at $3 per ounce \[ \text{Total cost of garlic powder} = 2 , \text{ounces} \times 3 , \text{dollars/ounce} = 6 , \text{dollars} \]
-
Calculate the total cost of the mixture:
- Total cost of the mixture is the sum of the total costs of the ingredients: \[ \text{Total cost of mixture} = \text{Total cost of oregano} + \text{Total cost of garlic powder} = 16 + 6 = 22 , \text{dollars} \]
Since \( y \) represents the total cost of garlic powder, we found that: \[ y = 6 \]
Thus, the value of \( y \) in the table is \( \boxed{6} \).
