Spots Company uses a standard cost system for its production process. Spots applies overhead based on direct labor hours. The following information is available for july:

Standard:
DLH per unit	2.20
Variable overhead per DLH	2.50
Fixed overhead per DLH(Based on 11,990 DLH)	$3.00
Actual:
Unit produced	4,400
Direct labor hours	8,800
Variable overhead	29,950
Fixed overhead	42,300
