A special order needs 200 hours of skilled labour.

Reveal answer & explanation
Correct answer: A) £5,600
Explanation
Moving workers means the other work is lost. Relevant cost = labour cost + contribution forgone = 200 x (£18 + £10) = £5,600. The wage cost is included because, when the other work is given up, its contribution is measured after charging that wage.
