The same employees are used to make all three product. Maximum demand for any product is 1000 per month. Available labour is $55,000 monthly
Cost to buy in 55 65 105
The answer for lost contribution per $ labour:
0.17 1.33 N/A
Please can you advise how they got this answer?
I should add, I understand the contribution per unit to make and contribution if bought.
The variable cost of making X is 20 + 30 = 50.
Therefore the extra cost of buying X externally is 55 – 50 = 5 per unit.
The labour cost is 30 per unit.
Therefore the extra cost per $ of labour = 5/30 = 0.17
The same for the others.
Do watch my free lectures on make and buy. The lectures are a complete free course for Paper F5 and cover everything needed to be able to pass the exam well.
Thank you for your help John and happy new year! 🙂
