An algal bloom covers 50m² of the surface of an isolated lake. The bloom grows at the rate of 80% every day. If the bloom covers the entire surface of the lake all plant and animal life in the lake will die. The Environmental Protection Agency can only get a team to the lake over land, a journey of 3 days. If the surface of the lake has a total area of 550m², will the team arrive in time to save the lake? How long would it take for the bloom to cover 500m² of the lake surface?
