Direction Please read the questions carefully. Please draw the cash flow diagrams and explain the steps that you are going to approach to solve the problems then solve the problem. Show the details in solving the problems. Please write legible hand writing, otherwise there is a deduction from your grade 10 points. Missing Cash Flow Diagram is deductible points equal to 20% of the total points for each question. Q1- A West Virginia coal mining operation has installed an in- shaft monitoring system for oxygen tank and gear readiness for emergencies. Based on maintenance patterns for previous systems, costs are minimal for the first few years, increase for a time period, and then level off. Maintenance costs are expected to be $150,000 in year 3, $175,000 in year 4, and amounts increasing by $25,000 per year through year 6 and remain constant thereafter for the expected 10-year life of this system. If similar systems will replace the current one, determine the perpetual equivalent annual maintenance cost at i=10% per year. Q2) A West Virginia coal mining operation has installed an in- shaft monitoring system for oxygen tank and gear readiness for emergencies. Based on maintenance patterns for previous systems, costs are minimal for the first few years, increase for a time-period, and then level off. Maintenance costs are expected to be $150,000 in year 3, and increase by 5% per year through year 6 and remain constant thereafter for the expected 10-year life of this system. If similar systems will replace the current one, determine the perpetual equivalent annual maintenance cost at i=10% per year
