Sharon drinks three glasses of chardonnay over a 180-minute period, each glass containing 1.6 standard drinks.
Sharon weighs 78 kilograms, and her blood alcohol content (BAC) at the end of this period can be calculated using the following formula:
\(\text{BAC}_{\text {female }}=\dfrac{10 N-7.5 H }{5.5 M}\)
| where \(N\) | = number of standard drinks consumed |
| \(H\) | = the number of hours drinking |
| \(M\) | = the person's mass in kilograms |
The spreadsheet below can be used to calculate Sharon's \(\text{BAC}\).
