Franco weighs 175 pounds and has consumed 5 drinks over the last 4 hours. What is his estimated BAC level?

1. 0.03

2. 0.06

3. 0.09

4. 0.12

The correct answer is: 0.06

To estimate Franco's Blood Alcohol Concentration (BAC) level based on his weight and the number of drinks consumed, we can consider some basic principles of alcohol metabolism. A common formula used is that one standard drink typically raises a person's BAC by about 0.02% for an average person weighing around 150 pounds, and this can vary based on numerous factors like metabolism and the type of beverage consumed. Franco weighs 175 pounds, which is slightly above the typical reference weight used in BAC calculations. He's consumed 5 drinks over 4 hours. Generally, alcohol is metabolized at a rate of about 0.015% per hour, meaning that over 4 hours, it would reduce his BAC to some extent. Assuming each of the 5 drinks raises his BAC by approximately 0.02%, that would initially suggest an increase of about 0.10%. Over the course of 4 hours, we would then subtract approximately 0.06% (4 hours x 0.015%). Therefore, this calculation leads to an estimated BAC level around 0.04%, suggesting that the most accurate estimation, given the variables involved, would be closer to 0.09%. Thus, the correct estimate of Franco's BAC
