Answer 1

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

In a 4 minute, the shower uses an average of 20-40 gallons of water,

If we consider the maximum gallons of water,

In 4 minutes, the maximum gallons of water = 40

In 1 minute, the maximum gallons of water is given by

In 18 minutes, the maximum gallons of water is given by

Hence, Option 'D' is correct.

Answer 2

4 / 40 = 18 / x.....4 min to 40 gall = 18 min to x gall
cross multiply
(4)(x) = (40)(18)
4x = 720
x = 720/4
x = 180 gallons <==
