Final answer:
Max's exact blood alcohol concentration (BAC) cannot be calculated with the provided details because individual metabolism and the exact type of drinks are unknown, but after 5 drinks, Max's BAC is likely at or above the typical legal intoxication limit of 0.08%.
Step-by-step explanation:
The question does not provide enough information to directly calculate Max's blood alcohol concentration (BAC); moreover, BAC calculations based on the amount of alcohol consumed involve several variables, including body weight, sex, metabolism rate, and the type of alcohol consumed. The body metabolizes alcohol at an approximate rate of 0.015 BAC per hour. Without the exact volume and type of the drinks consumed, an accurate calculation is not possible. However, we can discuss that after consuming 5 drinks in about an hour, a person weighing 180 pounds is likely to have a BAC that could be considered legally intoxicated, which is a BAC at or above 0.08% in most US states.
It's crucial to note that the effect of alcohol can vary widely from person to person, and the level of impairment for Max cannot be precisely determined with the given information. Furthermore, the Breathalyzer is an instrument commonly used to estimate BAC in field conditions. The metabolism of alcohol is a biological process that can be influenced by numerous factors, including the individual's health condition and the presence of food in the stomach. Despite these variations, it's recognized that no amount of alcohol is considered safe for driving, and driving skills are typically impaired even with a BAC as low as 0.02%.
