Answer:
0.025
Explanation:
Blood alcohol level is measured as the concentration of alcohol per unit of blood in the body. It is a good indication of how intoxicated a person is.
This can be measured by testing breathe, blood and even urine.
It is not a good system to measure how many drinks a person has had, since body weight, metabolism, health, etc. varies among different people, so testing the blood alcohol level is a good system to use.
