Problem 7

Water pollution A contaminant is leaking into a lake at a rate of Rstd 1600e 0.06t gallonsyh Enzymes have been added to the lake that neutralize the contaminant over time so that after t hours the fraction of the contaminant that remains is Sstd e20.32t . If there are currently 10,000 gallons of the contaminant in the lake, how many gallons are present in the lake 18 hours from now?
