5. Cook County Illinois estimates that a typical family household normally uses between 35 and 40 units of water per three-month billing cycle. A unit of water is approximately 750 gallons and flushing the toilet and taking showers are the largest uses of water. a) Chicago itself has a population around 2.7 × 106 residents. If a household is approximately 4 people, then how many gallons does each Chicago household use each day? b) How many gallons per second must be pumped from Lake Michigan to supply the city? c) Lake Michigan holds 1.3 x 1015 gallons of water. If just Chicago removed water from the lake and it never rained again, how many days would the water last?
