Q2) A West Virginia coal mining operation has installed an in-shaft monitoring system for oxygen tank and gear readiness foremergencies. Based on maintenance patterns for previoussystems, costs are minimal for the first few years, increase for atime-period, and then level off. Maintenance costs are expectedto be $200 in year 3, and increase by 5% per year through year 6and remain constant thereafter for the expected 10-year life ofthis system. If similar systems will replace the current one,determine the perpetual equivalent annual maintenance cost ati=10% per year.

The perpetual annuity is a series of uniform cash flows that occur in an equal interval between the…

Required information Assume that 25 years ago your dad invested $380,000, plus $31,000 in years 2 through 5, and $42,000 per year from year 6 on. Determine the annual retirement amount that he can withdraw forever starting next year (year 26), if the $42,000 annuity stopped at year 25. The interest rate being 11% per year.

The heat loss through the exterior walls of a certain manufacturing plant is estimated to cost $29000 at EOY 1. ABC Insulation, Inc., told the owner of the plant that the heat loss can be reduced by 80% if he is willing to spend $401,000 to install its innovative insulation material. The cost of heat loss is expected to rise by $2100 per year (uniform gradient) after the next year. The owner plans to keep the present building for 15 more years. Assume MARR (minimum acceptable rate of return) is 4% per year. (a) What is the present equivalent value of the cost savings in the reduction of heat loss for these 15 years? Round off your final answer to nearest thousand. (b) Using AW method, would you recommend the owner to install ABC's new insulation material? Why?
Problem 02.038 - Calculation of unknown base cash flow The future worth in year 10 of an arithmetic gradient cash flow series for years 1 through 10 is $600,000.

A material-handling system is available that will reduce this year’s labor costs by RM27500. The equipment is expected to last for 10 years. Labor costs increase at a rate of 5% per year and the interest rate is 11% per year. (i) What is the maximum amount that we could justify spending for the system? Include a cash flow diagram in your solution. (ii) What is the uniform annual equivalent value (A) of the labor costs over the 10-year period?
Milwaukee Machine Tool is planning to buy a machine for S15,000 with a salvage value of 20% of the initial cost after a life of 10 years. The company estimates it will need $900 for supplies, $250 for maintenance, $100 for utilities and S1,500 for overhead. They estimate these will increase by S1200, 8%, 10% and $200 respectively over the 10-year machine life. If interest rate is 5% per year, what is the net present value of the project? -$78,301.03 2 -$82,216.08 3 -$93,301.03 -$52,216.08

An investment carns P50,000 at the end of the 1st year and decreases by P5,000 every year thereafter. It has also been predetermined that a fixed annual cost of P5,000 is spent for maintenance and repairs. If the life of the investment is 10 years, determine whether this is a good investment assuming an investment cost of P162,049 and carning 10% per year. (25) #1: Annual method.

Problem 03.015- Annual worth calculations Improvised explosive devices (IEDs) are responsible for many deaths in times of strife and war. Unmanned ground vehicles (robots) can be used to disarm the IEDs and perform other tasks as well. If the robots cost $125,000 each and the military arms unit signs a contract to purchase 4,000 of them now and another 7,500 one year from now, what is the equivalent annual cost of the contract over a 8.00-year period at 12.00% per year interest? (Round the final answer to three decimal places.) The equivalent cost of the contract is determined to be $
