moody corportation uses a job$-$costing system with a plantwide predetermined rate based on machine hours. at the beginning of the year the compant made the following estimates.

machine hours required to support estimated production $160,000$

fixed manufacturing overhead cost $$650,000$

variable manufacturing overhead cost per machine hour $$4\mathrm{.}20$

$1.$ compute the plantwide predeteremined overhead rate.

$2.$ during the year, job $400$ was started and completed. the following information pertains to this job:

direct materials $$360$

direct labor costs $$290$

machine hours used $38$

compute the total manufacturing cost assigned to job $400$

$3.$ if job $400$ includes $60$ units what is its unit product cost?

$4.$ if moody uses a markup percentage of $120\%$ of its toal manufacturing cost, then what selling price per unit would it establish for job $400?$
