Patel and Sons Inc. uses a standard cost system to apply factory overhead costs to units produced. Practical capacity for the plant is defined as 51,900 machine hours per year, which represents 25,950 units of output. Annual budgeted fixed factory overhead costs are $259,500 and the budgeted variable factory overhead cost rate is $2.60 per unit. Factory overhead costs are applied on the basis of standard machine hours allowed for units produced. Budgeted and actual output for the year was 19,600 units, which took 40,900 machine hours. Actual fixed factory overhead costs for the year amounted to $252,700 while the actual variable overhead cost per unit was $2.50.

Based on the information provided above, what was (a) the fixed overhead spending (budget) variance for the year, and (b) the production volume variance for the year? Indicate whether each variance was favorable (F) or unfavorable (U). (Do not round intermediate calculations. Round final answers to the nearest whole dollar amount.)
