Gerhan Company's flexible budget for the units manufactured in May shows $15,610 of total factory overhead; this output level represents 70% of available capacity. During May, the company applied overhead to production at the rate of $3 per direct labor hour (DLH), based on a denominator volume level of 5,940 DLHs, which represents 90% of available capacity. The company used 5,000 DLHs and incurred $16,700 of total factory overhead cost during May, including $8,800 for fixed factory overhead. What is the variable factory overhead spending variance (to the nearest whole dollar) in May, assuming Gerhan uses a four-variance breakdown (decomposition) of the total overhead variance? (Round your intermediate calculation to 2 decimal places.)
