Your company has just purchased a new machine that costs $10,000. The machine has an expected life of 10 years and salvage value of $700. The depreciation life is 10 years. Compare the present values of the depreciation that would be obtained, using SL, SOYD, DDB, or a combination of two methods. Ignore Sec. 179.

I only need to compare SL ( Straight Line) and DDB(double declining balance). Assume a 10% minimum attractive rate of return.
