Question

People use water to​ cook, clean, and drink every day. An estimate of 21.2​% of the water used each day is for cooking. If a family uses 68.9 gallons of water a day for cooking​, how many gallons do they use every​ day?

Answer 1

260 gallons are used every day

Answer 2

Answer: 260 gallons
Explanation:
An estimate of 26.5​% of the water used each day is for cleaning and a family uses 68.9 gallons of water a day for cleaning​,
Percentage of water used for cleaning= 26.5%
Gallons of water used for cleaning= 68.9
Let the number of gallons used everyday be represented by g. This will give:
26.5% of g = 68.9
26.5/100 × g = 68.9
0.265 × g = 68.9
0.265g = 68.9
Divide both side by 0.265
0.265g/0.265 = 68.9/0.265
g= 260
260 gallons of water are used everyday.
