The Fairfold family decided to buy a super ski and water sports boat. They took out an $80,000, 5-year, 6% per year, compounded semiannually loan with monthly payments from First Bank and Trust (FB&T). After making only two payments, a banker friend offered to make them a better deal: a 5?year, 4.2% per year, compounded semiannually loan with no transfer fee to his bank and a complete repayment no-fee-required of the remaining principal to FB&T. The principal on the new loan will be the remaining principal from the current loan. Answer the following questions for the Fairfolds as they deliberate this new offer.
(a) What is the current monthly payment on the $80,000 loan? (b) What is the current principal due on the current loan? (c) How much interest have they already paid in the first two payments? (d) What is the amount of the new monthly payment starting with month 3, if the new loan offer is accepted?
Dickinson, a large oil and gas drilling and operating corporation, has invested over the past 6 years in the installation and operation of a FOUNDATION Fieldbus H1 (FF H1) system developed by Pepperl+Fuchs of Germany. A project engineer has collected information on annual net cash flow increases (?NCF) generated by the FF H1 system and the annual investments made by Dickinson in the system. At an interest rate of 10% per year, determine the PI of this endeavor. Has it proven to be economically worthwhile? (Note: Problem 9.54 explores the fieldbus implementation further using a spreadsheet.)
