1) Direct Labour
= 7 x 600
= $4,200

2) Factory Overhead
= 20% x 4200
= $840

3) T-shirts replaced
= cost per t-shirt x 20
= (4800/600) x 20
= 8 x 20
= $160

4) Additional labour incurred on t-shirts
= labour on reworked t-shirts + labour on replacement t-shirts
= 60 + (7 x 20)
= $200

Workings
5) Overhead incurred on additional labour
= 20% x 200
= $40

6) Cost incurred on reworked t-shirts
= 20 x 1
= $20

7) Sale of reworked t-shirts
= 20 x 10
= $200

Question 2

(iii)
If the true cost could be determined, each t-shirt produced in a
