Walkenhorst Company's machining department prepared its $2022$ budget based on the following data:

Practical capacity

Standard machine hours per unit

Standard variable factory overhead

Budgeted fixed factory overhead

$40,000$ units

$2$

$$3\mathrm{.}00$ per machine hour

$$440,000$

The department uses machine hours to apply factory overhead to production. In $2022,$ the department used $86,000$ machine hours

and incurred $$700,000$ in total manufacturing overhead cost to manufacture $42,090$ units. Actual fixed overhead cost for the year was

$$453,000.$

Required:

Determine for the year:

The predetermined fixed, variable, and total factory overhead application rates $($per machine hour$).($Round your answers to $2$

decimal places.$)$

The total factory overhead cost in the flexible budget based on output achieved in $2022.$

The fixed overhead volume variance. State whether this variance was favorable $($F$)$ or unfavorable $($U$).$

The variable overhead efficiency variance. State whether this variance was favorable $($F$)$ or unfavorable $($U$).$

The variable overhead spending $($rate$)$ variance and the fixed overhead spending $($budget$)$ variance. State whether each variance is

favorable $($F$)$ or unfavorable $($U$).$
