Limestone Construction purchased a concrete mixer on July 15, 2011. Company officials revealed the following information regarding this asset and its acquisition:

Purchase price....................\$210,000

Residual value...................................\$20,000

Estimated useful life...................................9 years

Estimated service hours...................................50,000

Estimated production in units.......................................375,000 yards

The concrete mixer was operated by construction crews in 2011 for a total of 6,500 hours, and it produced 49,500 yards of concrete.

It is company policy to take a half-year's depreciation on all assets for which it used the straight-line or duble-decllining balance depreciation method in the year of purchase.

1) Double-declining balance
2) Productive output
3) Service hours
4) Straight-line.
