Dexter Company assigns overhead (OH) cost based on direct labor hours (DLH). The $10/DLH pre-determined overhead rate is determined as follows: $7/DLH variable OH and $3/DLH fixed OH ($2,160/720DLH). 720 DLH reflects the capacity hours of producing 240 units (240 units X 3DLH/unit). Please note that it takes three direct labor hours to produce each unit of product.

During the period, 230 units were produced at the following cost:

Direct materials (1900 pounds @ $2.6/lb)	$4,940
Direct labor (700 hours @$11.60/hour)	8,120
Manufacturing OH ($4,300 variable OH and $2,000 fixed OH)	6,300
Total	$19,360

Compute the variable overhead spending variance (please use a negative sign if the variance is unfavorable. For example, if there is an unfavorable variance of $500, write -500. If there is a favorable variance of $500, write 500. Don't use $ signs in writing your answer)
