A state is planning to construct a new water treatment plant tomeet the increasing demand for clean drinking water.The proposed plant is designed to treat 50 million gallons of water per day (MGD). Ifthe average daily water consumption per person is 100 gallons, and the state'spopulation is expected to grow by 2% annually over the next five years, calculate:1. The current population served by the water treatment plant.2. The projected population to be served by the water treatment plant in fiveyears.3. The total water demand in the state per day currently.4. The total projected water demand in the state per day in five years.

QUESTION 3: Mr. Daily moves to a new province and has the option to either use prepaid electricity or metered electricity. He requests a comprehensive summary of the costs per kWh of electricity consumed and decides to analyse the information received. He summarizes it in the table below. Use the information to provide answers to Mr. Daily's questions below. Metered electricity A service fee of R115.20 per month is charged for metered electricity (VAT excluded). Electricity is charged at RO.80 per kWh. Prepaid electricity No service fee is charged for prepaid electricity. Electricity is charged at R1.20 per kWh. The first 100 units are free. Cost ( Prepaid elec) Cost ( Metered elec) = R115.20 + R0.80 × (number of units used – free units) —D R1.20 x питber of units used
3. Half-lives. Glyphosate is the active ingredient in some herbicides (weed killers) such as RoundupⓇ, Rodeo®, and Accord®, and is typically sprayed onto agricultural fields and forests. When glyphosate lands on plants, it is quickly absorbed through the leaves; in high enough concentration, glyphosate will kill a plant in 24 hours. Glyphosate that lands on soil eventually breaks down, although it can kill microorganisms that are beneficial to the soil. The average half-life of glyphosate in soil is 40 days-sometimes more or less depending on soil conditions. Recommended application rates of glyphosate vary from 0.3 to 4.0 pounds per acre." [9 pts total] a. With a half-life of 40 days, determine the daily decay rate of glyphosate in soils. Report 2 significant figures and include units. b. Suppose that 4 pounds of glyphosate are applied to a 1-acre agricultural field, with 1 pound landing on the soil. Compute the number of days until the glyphosate in the soil breaks down to 0.25…

A regional municipality is studying a water supply plan for its tri-city and surrounding area to the end of year 2070. To satisfy the water demand, one suggestion is to construct a pipeline from a major lake some distance away. Construction would start at the beginning of 2030 and take five years at a cost of $30 million per year. The cost of maintenance and repairs starts after completion of construction and for the first year is $3 million, increasing by 2 percent per year thereafter. At an interest rate of 7 percent, what is the present worth of this project? Assume all cash flows take place at year-end. Consider the present to be the end of 2025/beginning of 2026. Assume there is no salvage value at the end of year 2070. Click the icon to view the table of compound interest factors for discrete compounding periods when i = 7%. The present worth of this project is $ (Round to two decimal places as needed.) million.
