Explanation of Solution

Given information:

$12$ ounce bottle is for $\$1.25$

$16$ ounce bottle is for $\$1.50$

Formula Used:

Cost of bottle per ounce $=$ Total Capacity/ Total Price

Calculation:

Since, Cost of bottle per ounce $=$ Total Capacity/ Total Price

Thus, Cost of bottle per ouncefor $12$ ounce bottle $=\frac{12}{1.25}$

Simplifying further, cost of bottle per ouncefor $12$ ounce bottle is $9.6$

And Cost of bottle per ouncefor $16$ ounce bottle $=\frac{16}{1.50}$

Simplifying further, cost of bottle per ouncefor $16$ ounce bottle is $10.67$

Thus, comparing both the values, $10.67>9.6$

Hence, $16$ ounce bottle costs more per ounce.
