A numerically controlled milling machine was purchased for

$$95,000.$ The estimated salvage value was $$15,000$ after $15$ years.

What is the machine$$s book value after $5$ years of depreciation? If

the machine is sold for $$20,000$ early in Year $7,$ how much gain on

sale or recaptured depreciation is there? Assume

$($a$)$ Straight$-$line depreciation

$($b$)150\%$ declining balance depreciation

$($c$)80\%$ bonus depreciation with the balance using $7-$year MACRS

depreciation

$($d$)7-$year MACRS depreciation
