Work Step by Step

Consider the body weight to be 220-Pound. $w=220\text{-Pound}\ \text{Person}$ Consider the given equation. $BAC=\frac{600n}{w\left( 0.6n+169 \right)}$ Now, substitute the value of $n$from 1 to 10 and the value of $w$as 220-Pound in the above equation. The BAC with 0.08 or higher is illegal to drive. This shows that the person can have 5 drinks without exceeding the legal measure of drunk driving.
