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 3 4 Concentration 38.1 31.2 28.6 26.9 25.4 (ug/cm³) The data in the table can be modelled by h = a +b In C, whereh 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).
