A man who weighs approximately 140 pounds has two, 12 ounce beers and one 1 1/2 oz. shots of liquor in one hour. what is his estimated BAC?

Around. 8 B. A. C because if you look at scales online a 12 ounce beer is one drink and a 1 1/2 oz. shot is another full drinks. So that's 3 drinks which means its around a. 8 for a 140 pound man.

The correct answer is:

0.08.

Explanation:

To calculate the BAC, we first find the amount of alcohol (in grams) of the drinks. In the US, a standard drink has 14 g of alcohol. The man has 2 beers and 1 shot; this is 3 standard drinks:

3*14 = 42

This has 42 g of alcohol.

Next we convert the weight in pounds to grams. We do this by multiplying by 454:

140*454 = 63560

Next we multiply by the gender constant. For men, this is 0.68:

63560 (0.68) = 43220.8

We divide the grams of alcohol by this number:

42/43220.8 = 0.000972

Multiply this by 100:

0.000972 (100) = 0.0972

This is the BAC right after drinking. To account for the time that has passed, we multiply the number of hours by 0.015:

1 (0.015) = 0.015

We subtract this from our immediate BAC:

0.0972-0.015 = 0.0822 ≈ 0.08
