Landen Corporation uses a job$-$order costing system. At the beginning of the year, the company made the tollowing estimates:Machine$-$hours required to support estimated production $52,500$

Fixed manufacturing overhead cost $ $294,000$

Variable manufacturing overhead cost per direct labor$-$hour $ $3\mathrm{.}00$

Variable manufacturing overhead cost per machine$-$hour $ $ $\%\mathrm{.}00$During the year, Job $550$ was started and completed. The following information is available with respect to this job:Direct labor cost $ $293$

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:

a$.$ Compute the plantwide predetermined overhead rate.

b$.$ Compute the total manufacturing cost of Job $550.$

c$.$ 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:

a$.$ Compute the plantwide predetermined overhead rate.

b$.$ Compute the total manufacturing cost of Job $550.$

c$.$ 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.
