Solomon Corporation estimated its overhead costs would be $22,400 per month except for January when it pays the $179,700 annual Insurance premium on the manufacturing facility. Accordingly, the January overhead costs were expected to be $202,100 ($179,700+ $22,400). The company expected to use 7,800 direct labor hours per month except during July, August, and September when the company expected 9.100 hours of direct labor each month to build inventories for high demand that normally occurs during the Christmas season. The company's actual direct labor hours were the same as the estimated hours. The company made 3,900 units of product in each month except July, August, and September, in which it produced 4,550 units each month. Direct labor costs were $23.90 per unit, and direct materials costs were $10.60 per unit. Required a. Calculate a predetermined overhead rate based on direct labor hours. b.
