Chang industries has 1,400 defective units of product that have already cost $13.40 each to produce. a salvage company will purchase the defective units as they are for $4.40 each. chang's production manager reports that the defects can be corrected for $6.60 per unit, enabling them to be sold at their regular market price of $19.80. the incremental income or loss on reworking the units is:

Microsoft's stock price peaked at 6118% of its ipo price more than 13 years after the ipo suppose that $10,000 invested in microsoft at its ipo price had been worth $600,000 (6000% of the ipo price) after exactly 13 years. what interest rate, compounded annually, does this represent? (round your answer to two decimal places.)

True or false: a fitted model with more predictors will necessarily have a lower training set error than a model with fewer predictors.

You are evaluating two different silicon wafer milling machines. the techron i costs $285,000, has a three-year life, and has pretax operating costs of $78,000 per year. the techron ii costs $495,000, has a five-year life, and has pretax operating costs of $45,000 per year. for both milling machines, use straight-line depreciation to zero over the project’s life and assume a salvage value of $55,000. if your tax rate is 24 percent and your discount rate is 11 percent, compute the eac for both machines.
