As a percentage of the initial cost, what is the straight-line depreciation rate of the equipment? 6. The annual depreciation of P25,000 has been reserve for a machine for a machine using straight line for 10 years. If the first cost is P300,000, determine the salvage value of the machine. 7. An equipment costs P15,000 with a salvage value of P800 at the end of 12 years. Calculate the annual depreciation by sinking fund method with 30% interest. 8. Water pipe has a first cost of P35,000 and has no salvage value after 20 years, using sinking fund depreciation, determine the annual depreciation for 20% interest.
