The Hub Store at a university in eastern Canada is considering purchasing a self-serve checkout machine similar to those used in many grocery stores and other retail outlets. Currently the university pays part-time wages to students totalling $57,000 per year. A self-serve checkout machine would reduce parttime student wages by $37,000 per year. The machine would cost $280,000 and has a 10-year useful life. Total costs of operating the checkout machine would be $5,400 per year, including maintenance. Major maintenance would be needed on the machine in five years at a total cost of $10,400. The salvage value of the checkout machine in 10 years would be $42,000. The CCA rate is 25%. Management requires a 10% after-tax return on all equipment purchases. The company's tax rate is 30%. Required: 1. Determine the before-tax net annual cost savings that the new checkout machine will provide. $ 31,600 a 2-a. Using the data from (1} above and other data from the exercise, compute the checkout machine's net present value. (Hint Use Microsoft Excel to calculate the discount factor(s}.) (Do not round intermediate calculations and round your nal answer to the nearest dollar amount. Negative value should be indicated with minus sign.)
