Isometric Foundation Materials Company is calculating the variable overhead spending variance due to a difference in the actual variable overhead cost per unit of their cost per unit allocation base and the budgeted variable overhead cost per unit. Operational management had budgeted for a $65 variable overhead cost per unit but now find that the actual cost per unit of the allocation base is $60 per unit. The actual quantity of machine hours used was 5,500

Compute the variable overhead spending for IFMC and indicate whether it is a favorable (F) or unfavorable (U) variance.
