Question

In this question, you will calculate the cost of water for laundry and bathing. You will use the City of New York 2014 rate of $9.27/100 cubic feet of water. Calculate the cost of each of the following based on this rate. Use the conversion factor of 7.48 gallons per cubic foot (NYC Environmental Protection, 2014). A standard washing machine uses approximately 50 gallons of water per load (NYC Environmental Protection, 2014). A household washes one load of laundry per week for 52 weeks. Find the total cost per year. Round to the nearest dollar per year.

Answer 1

50 gal/ 7.48 gal = 6.68 ft^3 of water per wash.

 

Each wash = $9.27/100*6.68 = $.61 per wash

 

For whole year cost would be 52 * .61 = $32.20
