Answer:
a. Job 40 Job 42
Direct material 200*24= $4,800 900*18= $16,200
Direct labor 700*24= $16,800 1000*10 = $10,000
Overhead applied 700*6= $4,200 1000*6 = $6,000
Total Job cost $25,800 $32,200
b. Job 40 cost per unit = $25,800/1000 units
Job 40 cost per unit = $25.8 per unit
Job 42 cost per unit = $32,200/500 units
Job 42 cost per unit = $64.4 per unit
