Answer:
Plant wide overhead absorption rate= $4.20
Total manufacturing cost = $945.9
Unit cost of job = $18.92
Step-by-step explanation:
Plant wide overhead absorption rate
= Budgeted overhead/Budgeted machine hours
= $656,000/156,000 machine hours
= $4.20
Total manufacturing cost of Job 400
= Direct material cost + Direct labour cost + Variable overheads + Fixed production overhead
= 380 + 220 + (38 × $4.90) +( 38× $4.20)
= $945.994
Unit cost of job 400
= Total manufacturing cost/ units of product
= $945.99/ 50 units
= $18.919
= $18.92
