Alocal dairy farmer has a water tank (much like a water tower) on her farm to hold drinking water for her dairy cows. rain water which consists of 95% pure water, 2% minerals, and 3% other materials (such as leaves) collects in the tank. some water is lost through evaporation. the tank consists of a filtration process that creates a waste consisting of 8% water, 3% minerals, and 89% other materials. the drinkable water remaining after filtration consists of 98% pure water and 2% minerals. if the cows need 10,000 lb of water each week, how much rain water (by mass) must be collected weekly in the water tank?
