Question

an average tub bath uses 8 gallons of water, and an average shower uses 6 gallons. to provide baths for 60 people, how much more water will be needed if tubs are used instead of showers?

1. 30 gallons
2. 120 gallons
3. 360 gallons
4. 480 gallons

time left = 9 min

Explanation:

Step1: Calculate water used for baths

Each bath uses 8 gallons, and there are 60 people. So water for baths is \(8\times60 = 480\) gallons.

Step2: Calculate water used for tubs

Each tub uses 6 gallons, and there are 60 people. So water for tubs is \(6\times60=360\) gallons.

Step3: Find the difference

The difference in water usage is \(480 - 360=120\) gallons.

Answer:

120 gallons
