(a)

To determine

To calculate: The blood alcohol concentration (BAC).

The expression for BAC is,

$\text{BAC}=\frac{\left[\left(4\times 12\right)\times 3.2\times 0.075\right]}{190}-\left(2\times 0.015\right)$

(b)

To determine

To calculate: The blood alcohol concentration (BAC).

The expression for BAC is,

$\text{BAC}=\frac{\left[\text{ounces}\times \text{percent alcohol}\times 0.075\right]}{\text{body weight in lb}}-\left(\text{hours of drinking}\times 0.015\right)$.
