Problem 7-70A (Algorithmic) Depreciation Methods Hansen Supermarkets purchased a radio frequency identification (RFID) system for one of its stores at a cost of $150,000. Hansen determined that the system had an expected Ufe of seven years (or 50,000,000 items scanned) and an expected residual value of $7,600, Required: 1. Determine the amount of depreciation expense for the first and second years of the system's fe using the a. Straight-line method. Round your answer to the nearest whole dollar, and use the rounded amount for subsequent calculations. Depreciation expense: x per year b. Double-declining-balance method: (Round your answers to the nearest whole dollar and do not round intermediate calculations.) Depreciation Expense Year ! X Year 2 2. If the number of itemt scanned the nest and second years were 7.200,000 and 3,150,000, respectively, compute the amount of depreciation expense for the first and second years of the system's life using the units-of-production depreciation method. Round your answers to the nearest whole dollar and do not round intermediate calculations Depreciation Expense Year 2 3. Compute the book values for all three depreciation methods as of the end of the first and second years of the system's life.
