Question

People use water to​ cook, clean, and drink every day. An estimate of 27.4​% of the water used each day is for drinking. If a family uses 68.5 gallons of water a day for drinking​, how many gallons do they use every​ day?

Answer 1

68.5 x .274 = 18.769 gals of water a day

Answer 2

The common definition of a 3-day supply is 3 gallons per person—a gallon per person, per day—half to drink and a half to use for cooking and sanitation. The Centers for Disease Control and Prevention (CDC) even recommends drinking your half-gallon every day during an emergency, no matter what.
