Answer:
(a) The depreciable cost
depreciable cost = purchase cost - salvage value = $1,450,000 - $300,000 = $1,150,000
(b) The straight-line rate
straight line depreciation rate = 100% / useful life = 100% / 10 years = 10% per year
(c) The annual straight-line depreciation
annual straight line depreciation expense = depreciable value x deprecation rate = $1,150,000 x 10% = $115,000
