The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Correct Answer: 085 (0.10 – 0.015)<\/strong><\/h3>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Blood Alcohol Concentration (BAC) is the measure of alcohol in a person’s bloodstream. It’s commonly expressed as a percentage. The formula for estimating BAC is: BAC=Total Alcohol Consumed (grams)Body Weight (grams)\u00d7Widmark Factor\u2212Metabolism Rate\u00d7Time (hours)BAC = \\frac{\\text{Total Alcohol Consumed (grams)}}{\\text{Body Weight (grams)} \\times \\text{Widmark Factor}} – \\text{Metabolism Rate} \\times \\text{Time (hours)}<\/p>\n\n\n\n

Here\u2019s a step-by-step calculation for the situation:<\/p>\n\n\n\n

\n\n\n\n

Step 1: Calculate the total alcohol consumed<\/strong><\/h4>\n\n\n\n
    \n
  • 12 oz beer (two beers)<\/strong>: Each beer has 12 oz, and the average alcohol content is 5%. Alcohol\u00a0from\u00a0beer=2\u00d7(12\u2009oz\u00d70.05\u2009alcohol)=1.2\u2009oz\u00a0alcohol.\\text{Alcohol from beer} = 2 \\times (12 \\, \\text{oz} \\times 0.05 \\, \\text{alcohol}) = 1.2 \\, \\text{oz alcohol}.<\/li>\n\n\n\n
  • 112 oz shot of liquor<\/strong>: Assume the liquor is 40% alcohol by volume (ABV). Alcohol\u00a0from\u00a0liquor=112\u2009oz\u00d70.4=4.48\u2009oz\u00a0alcohol.\\text{Alcohol from liquor} = 112 \\, \\text{oz} \\times 0.4 = 4.48 \\, \\text{oz alcohol}.<\/li>\n\n\n\n
  • Total alcohol consumed<\/strong>: 1.2+4.48=5.68\u2009oz\u00a0alcohol.1.2 + 4.48 = 5.68 \\, \\text{oz alcohol}.<\/li>\n<\/ul>\n\n\n\n

    Convert ounces of alcohol to grams (1 oz = 28.3495 grams): 5.68\u2009oz\u00d728.3495=160.9\u2009grams.5.68 \\, \\text{oz} \\times 28.3495 = 160.9 \\, \\text{grams}.<\/p>\n\n\n\n

    \n\n\n\n

    Step 2: Apply the Widmark formula<\/strong><\/h4>\n\n\n\n

    The Widmark factor for men is 0.68. Body weight = 140 lbs. BAC=Total Alcohol (grams)Body Weight (grams)\u00d70.68.BAC = \\frac{\\text{Total Alcohol (grams)}}{\\text{Body Weight (grams)} \\times 0.68}.<\/p>\n\n\n\n

    Convert weight to grams (1 lb = 453.592 grams): 140\u2009lbs\u00d7453.592=63,503\u2009grams.140 \\, \\text{lbs} \\times 453.592 = 63,503 \\, \\text{grams}.<\/p>\n\n\n\n

    Substitute values: BAC=160.963,503\u00d70.68\u22480.0037\u2009(raw BAC).BAC = \\frac{160.9}{63,503 \\times 0.68} \\approx 0.0037 \\, \\text{(raw BAC)}.<\/p>\n\n\n\n

    \n\n\n\n

    Step 3: Adjust for metabolism and time<\/strong><\/h4>\n\n\n\n

    The body metabolizes alcohol at approximately 0.015 per hour. After one hour: Adjusted BAC=0.10\u22120.015=0.085.\\text{Adjusted BAC} = 0.10 – 0.015 = 0.085.<\/p>\n\n\n\n

    \n\n\n\n

    Conclusion<\/strong><\/h4>\n\n\n\n

    The estimated BAC is 0.085<\/strong>, matching the answer: 085 (0.10 – 0.015)<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
