c.
90 gallons of water
d.
180 gallons of water

Answer 1

d 180 gallons of water

Answer 2

Answer: Option 'D' is correct.

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

`(40)/(4)=10`

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

`18* 10=180\ gallons`

Hence, Option 'D' is correct.
