I'm very sorry to have to ask this...

I'm very sorry to bother you but I'm in need of some math help. This is not bullshit. A friend was recently at a frat party and one of the people had too much to drink and went to bed at 11pm. He got up at 7am and fell down some stairs and hit his head. When they did emergency surgery at 8am his blood alcohol was 0.10%. His blood alcohol would have peaked an hour after he stopped drinking(midnight) and would have absorbed at 0.015% per hour. My math isn't that good. I'm trying to find out what his peak alcohol % would have been at midnight. I'm very sorry to say the young man died. Thanks for your help.

With the legal liabilities, etc, involved in this, I for one would not even begin to touch this question. Please consider hiring a qualified professional. Your attorney may be able to provide you with some names. Good luck.

If y is linear, is 10 at x=0 and has a slope of 1.5, then the value of y at x=8 is 22. The key point here being IF Y IS LINEAR.

But if the alcohol "would have absorbed at 0.015% per hour" then it is not linear, it is exponential. If x is the amount of alcohol originally in the blood and the alcohol "would have absorbed at 0.015% per hour" then after t hours the amount of alcohol would be [math]0.015^7x[/math] (I am assuming that the 1.5% was intended and not "0.015%").

I am assuming that the 1.5% was intended and not "0.015%".

A rough estimate of the rate (for a 150-pound male) is -0.01% per hour, but many factors apply. Some of these factors are weight, percentage body fat, basal metabolic rate, medications, volume of food in the gut at drinking onset, how much food was consumed while drinking, condition of the liver.

The best that one can do in the absence of monitoring is to guess the rate.

-0.015% is probably an okay guess.
