Answer:
the family uses 300 gallons of water every day.
Explanation:
We can use a proportion to solve the problem:
drinking water used / total water used = drinking water percentage / 100
Let x be the total water used every day in gallons. Substituting the given values, we get:
69.3 / x = 23.1 / 100
To solve for x, we can cross-multiply and simplify:
69.3 * 100 = x * 23.1
6930 = 23.1x
x = 300
Therefore, the family uses 300 gallons of water every day.
