A proposed cost-saving device has an installed cost of $580,000. It is in Class 8 (CCA rate =208 ) for cCA purposes: it will actually function for five years, at which time it will have no value. There are no working capital consequences from the investment, and the tax rate is 35%. a. What must the pre-tax cost savings be for us to favour the investment? We require an 100 retum. (Hint: This one is a variation on the problem of setting a bid price.) (Do not round your intermediete calculations. Round the final answer to 2 decimal places. Omit $ sign in your response.) Cost savings b. Suppose the device will be worth $82.000 in salvage (before taxes). How does this change your answer? (Do not round your intermediate calculations. Round the final answer to 2 decimal places. Omit $ sign in your response.) Cost savings
