Conclusion
Put It Together
At the start of this module, we returned to Joan, whom we first met when she was drinking at a party. She was ready to drive home when we posed a question:- Given any amount that she drinks, can you figure out how much time should pass before she can drive safely and legally?
- B = percentage of BAC
- t = number of hours since the first drink
- N = number of “standard drinks” (a standard drink is one 12-ounce beer, one 5-ounce glass of wine, or one 1.5-ounce shot of liquor). N should be at least 1.
- W = weight in pounds
- g = gender constant: 0.68 for men and 0.55 for women

Now that we know about the algebra of inequalities, we can ask answer the new question about Joan.
- Given any amount that she drinks, can you figure out how much time should pass before she can drive safely and legally?
