If Max is 180 pounds and has had 5 drinks in an hour, what is his expected BAC?

To evaluate Max's expected Blood Alcohol Content (BAC) after consuming 5 drinks in an hour, we first consider the Widmark formula, which is commonly used to estimate BAC levels. The formula accounts for the amount of alcohol consumed, body weight, gender, and the distribution ratio of alcohol in the body.

Typically, a rough estimate for BAC is that one standard drink raises a person's BAC by approximately 0.02% to 0.03% for an average person. Since Max has consumed 5 drinks, if we consider the lower end of this range, his BAC would be approximately 0.10% to 0.15%.

For someone weighing 180 pounds, it’s reasonable to estimate that after 5 drinks in a short period, his BAC could align closely with the 0.11% level, aligning with the physiological effects of alcohol including impairment. This aligns well with the provided answer option, as it considers both his weight and the number of drinks consumed within a compressed timeframe.

Ultimately, evaluating the choices, a BAC of 0.11% accurately reflects the expected impairment for Max based on common guidelines and the calculation method used for estimating BAC levels.
