In a previous collaboration, you saw that a persons Blood Alcohol Content (BAC) after hours could be approximated by Widmarks equation. Paula is part of a research study to verify Widmarks equation. She weighs 135 pounds. The researchers ask her to drink four beers. After one hour, her BAC is at 0.13. After three hours her BAC is at 0.09.

Equation for research study model:

Recall Widmarks equation:

where is the number of standard drinks, is his/her weight in pounds, and gender constant (0.68 for men and 0.55 for women). One standard drink is a 12-ounce beer, 5-ounce glass of wine, or 1.5-ounce shot of liquor.

Simplify this equation for Paulas case, leaving as a variable.
