    Total cost (max) £15
    Lab cost/unit (£3)
    F cost per unit (£8)
    Max cost for material £4 per unit
    100 grams/unit
    So 1 kg = £40.00 max per kg

    i think it is

    total cost less fixed costs less labour cost

    £15-£8-£3 = £4 material cost per unit

    100 gms per unit - you can make 10 from 1 kg

    10 x £4 = £40 per kg

    Hope that makes sense?

    It asked "how much per kilogram?"

    As Taskey has shown, if 100g cost £4.00
    Then I kilogram costs £40.00


    (I will assume you know that there are 1,000 grams in 1 kilogram)

    Then 1 kilogram costs £40.00

    Material cost per unit
    kilograms per unit

    target labour time time per unit (minutes)

    Total target labour cost per unit
    Labour rate per minute

    First of all as the required profit margin is 40% this automaticly tells you that 40% of the sales price is the profit and 60% will be the cost, because we are trying to work out cost we do £25 x 0.60 (60%) which gives us £15 we know our fixed cost per unit are £8 and labour is 1/6 of a hour so if it is £18 for the hour but we only need 1/6 therefor labour is £3 so now we have the £8+£3=£11 leaving us £4 to spend on material as 100g is £4 therefor a kg must be £40 as there is a 1000g in 1 kg.
