In the United States, water used for irrigation is measured in acre-feet. An acre-foot of water covers an acre to a depth of exactly 1 ft. An acre is 4840 yd2. An acre-foot is enough water to supply two typical households for 1.00 yr. (a) If desalinated water costs $1950 per acre-foot, how much does desalinated water cost per liter?

Hi everyone today, we have a question telling us that de ionized water is sold in 4 55 gallon drums at a price of 1000, 559 and 96 cents. And our goal here is to calculate the price of de ionized water per liter. So we're going to start out with our 559 0. and that is per four Times 55 gallons. And then we're going to multiply that by one gallon over three .785 leaders Because one gallon equals 3.785 L. So our gallons are going to cancel out here and it's going to give us dollars per leader, So it will equal one point dollars per leader. And that is our final answer. Thank you for watching. Bye.
