20.A city with a population of 80,000 people covers an area of 10 miles by 12 miles. The city council wants to determine if it has enough groundwater resources to supply its population at the U.S. average rate of 1,400 gallons per person per day. Drilling has determined that there is a 20-foot thick aquifer under the entire city with a porosity of 20% and a specific yield of 5%. The city geologist has determined that the sustained yield is one-fiftieth of the specific yield. Up to how many gallons per person per day can this city pump water without lowering the water table? (There are 640 acres in a square mile and 325,851 gallons in an acre-foot.)

a.1,251 gallons per person per day

b.62,563 gallons per person per day

c.100,101,427 gallons per person per day

d.625,633,920 gallons per person per day

e.5,005,071,360 gallons per person per day
