Actual fixed factory overhead costs for the year amounted to $248,300 while the actual variable overhead cost per unit was $2.10. Based on the information provided above, calculate the following factory overhead variances for the year. Indicate whether each rariance is favorable (F) or unfavorable (U). (Do not round intermediate calculations. Round your final answers to nearest whole follar amount.)
