A manufactureris considering replacing a productionmachine tool. The new machine, costing $37,000,would have a life of 4 years and no salvage value,but would save the firm $5000 per year in directlabor costs and $2000 per year in indirect laborcosts.

An oil refinery must now begin sending its wasteliquids through a costly treatment process beforedischarging them into a nearby stream. The engi-neering department estimates costs at $300,000 forthe first year. It is estimated that if process and plantalterations are made, the waste treatment cost willdecline $30,000 each year. As an alternate, a spe-cialized firm, Hydro-Clean, has offered a contract toprocess the waste liquids for 10 years for a fixed priceof $150,000 per year, payable at the end of each year.Either way, there should be no need for waste treat-ment after 10 years. The refinery manager considers8% to be a suitable interest rate. Use an annual cashflow analysis to determine whether the Hydro-Cleanoffer should be accepted

Bill Anderson buys a car every 2 years as follows:initially he makes a down payment of$6000 on a$15,000 car. The balance is paid in 24 equal monthlypayments with annual interest at 12%. When he hasmade the last payment on the loan, he trades in the2-year-old car for $6000 on a new $15,000 car, andthe cycle begins over again.Doug Jones decided on a different purchaseplan. He thought he would be better off if he paid$15,000 cash for a new car. Then he would make amonthly deposit in a savings account so that, at theend of 2 years, he would have $9000 in the account.The $9000 plus the $6000 trade-in value of the carwill allow Doug to replace his 2-year-old car by pay-ing $9000 for a new one. The bank pays 6% interest,compounded quarterly.(a)What is Bill Andersons monthly payment to payoff the loan on the car?(b)After he purchased the new car for cash, howmuch per month should Doug Jones deposit inhis savingsaccountto haveenoughmoney for thenext car 2 years hence?(c)Why is Dougs monthly savings account depositsmaller than Bills payment?
