Explanation:

Step1: Calculate price per ounce for 10-ounce bottle

To find the price per ounce, divide the total price by the number of ounces. For the 10-ounce bottle, the price is $9.50. So, the price per ounce is $\frac{9.50}{10} = 0.95$ dollars per ounce.

Step2: Calculate price per ounce for 5-ounce bottle

For the 5-ounce bottle, the price is $5. So, the price per ounce is $\frac{5}{5} = 1$ dollar per ounce.

Step3: Compare the two prices per ounce

We have the price per ounce for the 10-ounce bottle as $0.95$ and for the 5-ounce bottle as $1$. Since $0.95 < 1$, the 10-ounce bottle has a lower price per unit (ounce).

Answer:

The 10-ounce bottle is a better deal because the price per unit is lower. (Corresponding option: The 10-ounce bottle is a better deal because the price per unit is lower.)
