Question

You've just consumed three 12-ounce ales that were labeled as having 8% alcohol. How much alcohol have you consumed? a) 2 ounces b) 3 ounces c) 2.4 ounces d) 3.2 ounces

Answer 1

b) 3 oz

Explanation:

3 12 oz ales with 8% alcohol.

One ale would contain (12 oz)*(0.08) alcohol.

(12 oz)*(0.08) = 0.96 oz alcohol

3 ales = 3*(0.96 oz) = 2.88 oz rounded to 2 sig figs makes this 2.9 oz.

The closest answer option is b) 3 oz.
