    Question 5
    Labour 5000 hrs existing labour rate is $8 p/hr
    Lost contribution is $12
    I thought the Labour rate is not relevant but it turned out to be relevant as the correct answer was $100,000 not $60,000

    Thanks

    If we take the labour to another job, we lose the revenue of $20 and we save the ‘other variable costs’ of $3 (we will still be paying the labour). So the net loss (and the relevant cost) is 20 – 3 = $17.

    This is always equal to the contribution + labour (12 + 5 = $17).

    So the net loss is 20 – 3 =
