According to one study, the average American shower lasts for 8.2 minutes and uses 17.2 gallons of water (Alliance for Water Efficiency, 2014). A person showers once a day for a year. Find the total cost per year.

We conclude that the average American shower needs 2984.8 minutes and 6260.8 gallons of water during the year.

Step-by-step explanation:

We know that the average American shower lasts for 8.2 minutes and uses 17.2 gallons of water. A person showers once a day for a year.

We know that one year have 52 weeks, and one week have 7 days.  

We calculate:

8.2 · 7 · 52= 2984.8 minutes.

17.2 · 7 · 52= 6260.8 gallons.

We conclude that the average American shower needs 2984.8 minutes and 6260.8 gallons of water during the year.

C = $64.12 per year

The total cost per year is $64.12

Incomplete Question, Here is the completed question:

You learned about a water footprint. Part of a person’s water footprint is the water used for cleaning. In this question, you will calculate the cost of water for laundry and bathing. You will use the City of New York 2011 rate of $7.64/100 cubic feet of water. Calculate the cost of each of the following based on this rate. Use the conversion factor of 7.48 gallonsper cubic foot.3

According to one study, the average American shower lasts for 8.2 minutes and uses 17.2 gallons of water (Alliance for Water Efficiency, 2014). A person showers once a day for a year. Find the total cost per year.

Step-by-step explanation:

Given:

Volume used per day = 17.2 gallons

Cost = $7.64/100 cubic feet

Conversion = 7.48 gallon/cubic feet

The total volume of water used in a year is;

V = 17.2 gallons/day × 365 days/year

V = 6278 gallons/year.

The volume used per year in cubic feet is;

V = 6278 gallons/year ÷ 7.48 gallons/cubic feet

V = 6278/7.48 cubic feet/year

The total cost per year C = volume × cost rate.

C = (6278/7.48) × $7.64/100

C = $64.12 per year

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
