Suppose That the Blood Alcohol Concentration (BAC) of a Person $\times \%$

Suppose that the blood alcohol concentration (BAC) of a person who has been drinking is given by the following:
Total oz consumed $\times \%$ alcohol $\times 0.075 \div$ body weight in $\mathrm{lb}-\mathrm{hr}$ of drinking $\times 0.015$ . Find the BAC for a 135-lb woman who, in $4 \mathrm{hr}$ , has drunk 9 beers. (Assume that each beer is $12 \mathrm{oz}$ with a $4.7 \%$ alcohol content.) Round your answer to the nearest thousandth.

A) 0.222
B) 0.217
C) 0.282
D) 0.267
