To estimate the Blood Alcohol Concentration (BAC) level, we need to consider Sheila's weight, the number of drinks consumed, and the time over which these drinks were consumed. For women, a rough guideline for estimating BAC is that one standard drink raises BAC by approximately 0.02% per drink when accounting for body weight and metabolism.

In this scenario, Sheila weighs 125 pounds and has consumed 3 standard drinks in a period of 2 hours. Typically, the body can metabolize about one standard drink per hour. Therefore, even though Sheila drinks 3 drinks, she has 2 hours for her body to process some of that alcohol.

First, we calculate the initial rise in her BAC based on her three drinks:

- 3 drinks would initially raise her BAC to approximately 0.06% (3 drinks x 0.02% per drink = 0.06%).

Next, we need to consider the alcohol metabolized over the 2 hours. If we assume she metabolizes roughly 0.015% BAC per hour, over 2 hours she would metabolize about 0.03%.

When we subtract the metabolized BAC from her initial rise:

- Her BAC would then be approximately 0.
