For direct materials, the standard quantity is 3 pounds/unit, the standard price is $6/pound, and the price variance for materials is isolated as soon as possible. Additionally, the standard price for direct labor price is $7/hr, and the standard price for variable factory overhead is $5/hr. The total overhead cost applied (SQxSP for both variable factory overhead and fixed factory overhead combined) for 40,000 units (which was their denominator level but not the actual units produced) is $880,000, of which $400,000 is variable factory overhead. Finally, the system provided the following additional information:

Direct Material efficiency variance is $240,000 U.

Variable factory overhead efficiency variance is $250,000 F.

Actual direct material used (requisitioned) is 220,000 lbs.

Actual direct material purchased is 320,000 lbs at $5.50/lb.

Actual direct labor costs are $660,000.

Actual direct labor hours worked are 70,000 hours.

Total actual factory overhead is $900,000.

Actual variable factory overhead is $470,000

1. Please answer the following:

a) Variable overhead spending variance is:

b) Fixed factory overhead flexible budget variance is:

c) The production volume variance is
