Answer 1

Answer:

Equation: 0.165 x = 69.3

x = 420 gallons

Explanation:

Let us call x the total number of gallons the family uses. then we know that 16.5 % (WHICH WE ARE TOLD IS 69. 3 GALLONS ) of it used for cooking, meaning

$\frac{16.5}{100}x=69.3$$0.165x=69.3$

Dividing both sides by 0.165 gives

$x=\frac{69.3}{0.165}$$x=420.$

Hence, 420 gallons of water are used each day by a family.
