Problem $11-22.$ A heavy construction firm has been awarded a

contract to build a large concrete dam. It is expected that a total

of $8$ years will be required to complete the work. The firm will

buy $$600,000$ worth of special equipment for the job. During the

preparation of the job cost estimate, the following utilization

schedule was computed for the special equipment:

Year Utilization $($hr$/$yr$)$

$16000$

$24000$

$34000$

$41600$

$5800$

$6800$

$72200$

$82200$

At the end of the job, it is estimated that the equipment can be

sold at auction for $$60,000.$

$($a$)$ Compute the straight$-$line depreciation schedule.

$($b$)$ Compute the unit$-$of$-$production depreciation schedule
