Answer 1

Answer:

Alex's approximate BAC at 10:00 am next morning is 2.66%

Question:

Alex’s friend’s wedding celebrations started with the rehearsal dinner on Friday, followed by the wedding ceremony and reception on next day evening. Everybody had a good time, and since there was an open bar, Alex had quite a few drinks with friends that he had not seen for a while. Alex has to drive back home on Sunday morning, and he needs to start driving fairly early since he has at least a 6-hour drive ahead of him. Alex had a few drinks too many during the reception. He does not remember exactly, but he thinks he had 2 martinis during cocktail hour, 3 glasses of wine with dinner, and two glasses of champagne during toasts, followed by 4 tequila shots with old buddies from school. The wedding reception started about 8:00 p.m. and lasted until midnight. Alex plans to wake up and start driving by 10:00 a.m. Alex is 27 years old and weighs 172 pounds. You will recall from the video, that blood alcohol concentration (BAC) depends on the amount of alcohol consumed, the individual’s gender and body weight, and the time since alcohol was consumed. Use the following equation to calculate BAC: BAC = [(number of standard drinks / 2) × (gender constant / body weight in pounds)] – (0.017 × hours)

Calculating Blood Alcohol Concentration After Time - What was Alex’s blood alcohol concentration at 10:00 AM next morning? Round the percentage of BAC to the second decimal place. During calculations, use numbers rounded to the third decimal place. When calculating standard drinks, use values rounded to the first decimal place. _____%

Explanation:

No. of drinks = 2 martinis + 3 glasses of wine + 2 glasses of champagne + 4 tequila shots

Number of standard drinks

1 martini = 1.5 standard drinks ⇒ 2 martinis x 1.5 = 3

1 glass of wine = 1.5 standard drinks ⇒ 3 glasses x 1.5 = 4.5

1 glass of champagne = 1.4  standard drinks ⇒ 2 x 1.4 = 2.8

1 tequila shot = 1 standard drink ⇒ 4 x 1 = 4

Total number of standard drinks = 3 + 4.5 + 2.8 + 4 = 14.3

Total number of standard drinks = 14.3, Age = 27 years, Weight = 172 lb, Gender constant = 0.68 (for Males), Hours since last drink = 10 hours (12:00am - 10:00am)

Using the equation:

BAC = [(number of standard drinks / 2) * (gender constant / body weight in pounds)] * 100% – (0.017 * hours)

BAC = $\frac{14.3 * 0.68 }{2 * 172} * 100 - (0.017 * 10)$

BAC = 2.83 - 0.17 = 2.66%

BAC = 2.66%

This means that Alex's approximate BAC at 10:00 am next morning is 2.66%
