Question

A 150 lb man has 2 beers, determine his BAC
BAC = ?​

Answer 1

Answer: BAC = 0.056%

Explanation:-

Data given;

Weight of the man = 150 lbs (Wt)

Number of drinks = 2 beers

We know that

A beer contains 5% (0.05) of alcohol (D)

1 bear = 12oz

So 2 beer = 2 × 12 = 24oz (A)

Derived from widmark formula;

BAC for Male = (A × D × 5.14) / ( Wt × 0.73 )

BAC for Female = (A × D × 5.14) / ( Wt × 0.66 )

WHERE

A = Alcohol consumed in ounces (oz.)

D = percentage of alcohol written as a decimal

Wt = weight of person in pounds (lbs.)

Using BAC for male

BAC for Male = (A × D × 5.14) / ( Wt × 0.73 )

We simply input our values

BAC = ( 24 × 0.05 × 5.14) / ( 150 × 0.73)

BAC = 6.168 / 109.5

BAC = 0.056%
