Answer: 260 gallons
Step-by-step 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.
Answer:
This familly uses 260 gallons dayly.
Step-by-step explanation:
Since we were given the amount of water this family uses for cleaning we can use a rule of three to know how many gallons they use dayly. This is done by realting 68.9 gallons to 26.5% and solving for 100%. We have:
68.9 gallons -> 26.5%
x gallons -> 100%
68.9/x = 26.5/100
26.5*x = 68.9*100
26.5*x = 6890
x = 6890/26.5 = 260 gallons
This familly uses 260 gallons dayly.
