Answer:
Yes
Step-by-step explanation:
the function that gives the alcohol level is:
where x is the number of hours.
we need to know if after 4 hours an average person is legally drunk, thus:
and we substitute this in the function:
solving these operations we obtain:
the alcohol level after 4 hours is 3.24.
Since a person is considered to be legally drunk if the level exceeds 1.5, and we obtained 3.24 which is greater than 1.5, a person who has been drinking for 4 hours under the conditions indicated by the problem would be considered legally drunk.
