If both can be answered that would be great. I just have to see how to set up these problems so I can solve the others.

Factory Overhead Controllable Variance Bellingham Company produced 3,200 units of product that required 3 standard hours per unit. The standard variable overhead cost per unit is $2.10 per hour. The actual variable factory overhead was $20,540. Determine the variable factory overhead controllable variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number. Factory Overhead Volume Variance Dvorak Company produced 5,200 units of product that required 4 standard hours per unit. The standard fixed overhead cost per unit is $2.85 per hour at 18,700 hours, which is 100% of normal capacity. Determine the fixed factory overhead volume variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number
