Question

People use water to cook, clean, and drink every day. An estimate of 15.5% of the water used each

day is for cooking. If a family uses 68.2 gallons of water a day for cooking, how many gallons do they use every day?

Answer 1

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
