Variance Analysis; Find Standard Time per Unit The Mahon Electrical Company manufactures special electrical equipment in Kowloon. The management has established standard costs for many of its operations and uses a flexible budget. Overhead is applied on a basis of standard labor-hours. The Transformer Assembly Department operates at the following standard rates:

STANDARD COSTS One Multiplex Transformer TR-906 Materials:
4 sheets soft iron, 9 < 16 in. @ $1.12 ea.
2 spools copper wire @ $2.39 ea.
Direct-labor rate $2.50 per hour Combined-overhead rate $2.10 per direct-labor hour The flexible budget indicates that total overhead would amount to $4,489 and $4,989 at production levels of 500 and 600 units, respectively. The production budget for the past month called for 2,340 direct-labor hours, $2,925 variable-overhead costs, and $1,989 fixed-overhead costs. Only 550 transformers were produced, at the costs listed below:
