the 10-ounce bottle is a better deal because you use it every day.

Explanation:

Step1: Calculate 10oz price per ounce

$\frac{\$9.50}{10} = \$0.95$ per ounce

Step2: Calculate 5oz price per ounce

$\frac{\$5}{5} = \$1.00$ per ounce

Step3: Compare unit prices

$\$0.95 < \$1.00$, so 10oz bottle has lower unit cost.

Answer:

The 10-ounce bottle is a better deal because the price per unit is lower.
