Landen Corporation uses a job$-$order costing system. At the beginning of the year, the company made the following estimates:

Direct labor$-$hours required to support estimated production $85,000$

Machine$-$hours required to support estimated production $42,500$

Fixed manufacturing overhead cost $ $238,000$

Variable manufacturing overhead cost per direct labor$-$hour $ $2\mathrm{.}20$

Variable manufacturing overhead cost per machine$-$hour $ $4\mathrm{.}40$

During the year, Job $550$ was started and completed. The following information is available with respect to this job:

Direct materials $ $208$

Direct labor cost $ $334$

Direct labor$-$hours $15$

Machine$-$hours $5$

Required:

Assume that Landen has historically used a plantwide predetermined overhead rate with direct labor$-$hours as the allocation base. Under this approach:

Compute the plantwide predetermined overhead rate.

Compute the total manufacturing cost of Job $550.$

If Landen uses a markup percentage of $200\%$ of its total manufacturing cost, what selling price would it establish for Job $550?$

Assume that Landen$$s controller believes that machine$-$hours is a better allocation base than direct labor$-$hours. Under this approach:

Compute the plantwide predetermined overhead rate.

Compute the total manufacturing cost of Job $550.$

If Landen uses a markup percentage of $200\%$ of its total manufacturing cost, what selling price would it establish for Job $550?$

Note: Round your intermediate calculations to $2$ decimal places. Round your Predetermined Overhead Rate answers to $2$ decimal places and all other answers to the nearest whole dollar.
