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

Practical capacity

Standard machine hours per unit $,40,000$ units

Standard variable factory overhead $$3,{00}^2$

Budgeted fixed factory overhead $$280,000$

The department uses machine hours to apply factory overhead to production. In $2022,$ the department used $86,100$ machine hours and incurred $$545,000$ in total manufacturing overhead cost to manufacture $42,100$ units. Actual fixed overhead cost for the year was $$290,000.$

Required:

Determine for the year:

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

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

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

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

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

The variable overhead spending variance and the fixed overhead spending variance. State whether each variance is favorable $(F)$ or unfavorable $($U$).$
