Hi I'd like help on these questions about inverse equations. Blood Alcohol Content About 3,800 people are arrested for driving under the influence of drugs or alcohol in Chicago each year BAC (Blood Alcohol Content) is amount of alcohol consumed, the person's gender, the person's weight, and the time since alcohol was consumed. The legal limit in most states tobe considered driving under the influence (DUI) is .08% for drivers over the age of 21 (for those under 21, there is a zero tolerance law-it is a DUI if any alcohol is present in the blood). as a percentage of ethanol in the blood. A person's BAC is a function of the Do you think that the BAC is directly or inversely proportional to the amount of alcohol consumed? What about the relationship between BAC and weight? The BAC varies directly with amount alcohol consumed and inversely with weight. Write the general equation of variation. y-x If a 120 pound woman drinks 2 tequila shots (1.5 oz each of 40% alcohol), her BAC would be .078%, just barely under the legal limit to drive. First, calculate the amount of alcohol consumed in those 2 shots. Then, calculate the value of the constant of variation, k. Rewrite the general equation with this constant. Use the equation to calculate the BAC for a 140 pound woman who drinks 4 glasses of wine (5 oz per glass of 12% alcohol), would she be considered legally drunk? This formula does not yet take into account time. What would happen to the BAC over time? How do you think we need to account for the time since drinking? The body eliminates alcohol from the system linearly at a rate of about .015% per hour. Rewrite the formula from above to account for this fact.

Explanation / Answer

Blood alcohol concentration is a function of the total amount of alcohol in one's system divided by total body weight.

So BAC is directly proportional to  amount of alcohol consumed and inversely proportional to body weight.
