Question

A) Find the BAC for the male student who weighs 180 lbs and has 5 beers after 5 hours. b) How long would it take the 180 lb male completely metabolize (BAC =0) five beers?

Answer 1

a) The formula for determining BAC is expressed as

B = - 0.015t + 2.84N/Wg

Where

g = gender constant = 0.68

n = number of drinks = 5

W = weight = 180 lbs

t = time = 5 hours

BAC = - 0.015 * 5 + 2.84 * 5/180 *0.68

BAC = - 0.075 + 14.2/122.4

BAC = - 0.075 + 0.116

BAC = 0.041

b) Given that BAC = 0, W = 180, N = 5, then

0 = - 0.015 * t + 2.84 * 5/180 *0.68

0 = - 0.015t + 14.2/122.4

0 = - 0.015t + 0.116

0.015t = 0.116

t = 0.116/0.015

t = 7.73

= 9.7 hours

It will take 7.7 hours
