Question
![An engineer who accidentally inhaled poisonous fumes was given treatment for it.
The concentration of poison in the engineer's blood was measured every hour.
The table below shows the record:
Hours Since
Inhal ati on
1
5
Concentration
38.1
31.2
28.6
26.9
25.4
ug/ cm)
The data in the table can be modelled by h = a +b lIn C, where h is the number of
hours since the accident and C is the concentration of poison in the blood.
If the engineer is allowed to return to work when the concentration of poison falls
below 0.2, how many days must they wait to return to work? (Round your answer UP
to the nearest day).
