To find the price per ounce, we first need to determine how many ounces are in a 2-pound bottle of ketchup.
1 pound is equal to 16 ounces. Therefore, a 2-pound bottle contains:
\( 2 , \text{pounds} \times 16 , \text{ounces/pound} = 32 , \text{ounces} \).
Now, if the bottle costs $8.00, we can calculate the price per ounce by dividing the total price by the total number of ounces:
\[ \text{Price per ounce} = \frac{\text{Total Price}}{\text{Total Ounces}} = \frac{8.00}{32} = 0.25. \]
So, the price per ounce is $0.25.
