a. Esther, Vida, and Clair were asked to consider two different cash flows: GHC1000 that they could receive today and GHc3000 that would be received 3 years from today. Esther wanted the GH1000 today, Vida chose to collect GH 3000 in 3 years, and Clair was indifferent between these two options. Which of the three women made the right choice? Explain. (10 marks) b. You bought a sachet water machine from Indie Inc. The cost of the machine was GHC35,000. At that time, you asked for the payment to be deferred, and a contract was written. Under the contract, you could delay paying for the sachet water machine if you purchased the material for packaging the water from Indie Inc. You will then pay for the machine in a lump sum at the end of 2 years, with interest at a rate of 2% per quarter-year. According to the contract, if you ceased buying the packaging material from Indie Inc. at any time prior to 2 years, the full payment due at the end of 2 years would automatically become due. One year later, you decided to buy the packaging material elsewhere and stopped buying from Indie Inc., whereupon Indie Inc., per the contract terms, asked for the full payment that is due at the end of 2 years to be paid immediately. You were unhappy about this, so Indie Inc. offered as an alternative to accept the GH35,000 with interest at 10% per semiannual period for the 12 months that you had been buying the packaging material from Indie Inc. Which of the alternatives should you accept? Explain. (10 marks)
