Question

Jim wants to know how much his family spends on water for showers. Water costs $1.50 for 1000 gallons. His family averages 4 showers per day. The average length of a shower is 10 minutes. He places a bucket in his shower and turns on the water. After one minute, the bucket has 2.5 gallons of water. About how much money does his family spend on water for showers in a 30 day month?

Answer 1

The correct answer is $4.50

Answer 2

1 min = 2.5 min
10 • 2.5 = 25 gallons for one shower
25 • 4 = 100 gallons of water per day
100 • 30 = 3000
1.5 = 1000
4.5 = 3000

The family spend $4.50 on water in 30 days.

Hope this helps!
