Sunny Corp. manufactures portable beds and chairs made of round steel bars and woven plastic strips (similar to woven rattan strips). The steel bars are cut, heated and bent before they are connected by bolts and nuts to form the desired structures. The woven plastic strips are subsequently attached per specifications. For 2014, estimated factory overhead (without the corresponding provision for any imperfection) is P 60,000 based on estimated direct labor cost of P 120,000. Per estimates, a 5% spoilage may be expected with unrecovered cost of P 3,000. For January, 2014, the company processed an order for 10 portable rocking chairs (job no. 027). The prime costs are as follows: P 10,000 5,000 Direct materials Direct labor Upon final inspection, two rocking chairs are found below standard. Estimated cost recovery is P 1,000 per chair.
