Management of Modugno Corporation is considering whether to purchase a new model 370 machine costing $443,000 or a new model 240 machine costing $404,000 to replace a machine that was purchased 12 years ago for $411,000. The old machine was used to make product M25A until it broke down last week. Unfortunately, the old machine cannot be repaired.

Management has decided to buy the new model 240 machine. It has less capacity than the new model 370 machine, but its capacity is sufficient to continue making product M25A.

Management also considered, but rejected, the alternative of simply dropping product M25A. If that were done, instead of investing $404,000 in the new machine, the money could be invested in a project that would return a total of $432,000.

In making the decision to buy the model 240 machine rather than the model 370 machine, the sunk cost was:

$404,000

$432,000

$411,000

$443,000

At the end of the year, actual direct labor-hours for the year were 22,500 hours, the actual manufacturing overhead for the year was $264,300, and manufacturing overhead for the year was overapplied by $5,700. If the predetermined overhead rate is based on direct labor-hours, then the estimated direct labor-hours at the beginning of the year used in the predetermined overhead rate must have been: (Round your intermediate calculations to 2 decimal places.)

	21,800 direct labor-hours
