Straight-line depreciation. Quick Copy buys an office machine for $5200 on January 1 of a given year. The machine is expected to last for 8 yr, at the end of which time its salvage value will be $1100. If the company figures the decline in value to be the same each year, then the straight line depreciation value,
a. Find the linear function for the straight-line depreciation of the machine.
b. Find the book value of the machine after 0 yr, 1 yr, 2 yr, 3 yr, 4 yr, 7 yr, and 8 yr.
