Answer:

13 cents

Step-by-step explanation:

$49.80 is INCLUDING tax of $1.92. So the cost before tax is:

49.8 - 1.92 = $47.88

This is the price of FOUR bottles. So price PER BOTTLE is:

47.88/4 = $11.97

This $11.97 is a 95 ounce bottle.

We need to find price PER OUNCE, so we divide the price by 95:

11.97/95 = $0.126 PER OUNCE

Rounded to 2 decimal, that would be around $0.13 per ounce
