Foundations of Mathematical Reasoning, In-Class Activities, Lesson 15.C 108 Recall Widmark's equation for BAC. In the case of the average male who weighs 190 pounds, you can simplify Widmark's formula to get 2) B = -0.015t+ 0.022N Forensic scientists often use this equation at the time of an accident to determine how many drinks someone had. In these cases, time (t) and BAC (B) are known from the police report. The crime lab uses this equation to estimate the number of drinks (N). Part A: Find the number of drinks if the BAC is 0.09 and the time is 2 hours. Part B: Since the lab uses the formula to solve for N over and over, it is easier if the formula is rewritten so that it is solved for N. In other words, N is isolated on one side of the equation and all other terms are on the other side. Solve for N in terms of t and B. Part C: Use the new formula to find the number of drinks if the BAC is 0.17 and the time is 1.5 hours. 3) Solve a + 2b = 12 for b. 4) -2 Solve y = for x. Зx-1 5) Solve C for B. D-A ster
