Current fixed production costs are £0.135 million.
Current labour cost per unit is £0.17 which is completely variable.
Current material cost per unit is £0.63 and is completely variable.

Variable material cost of the new product will be £0.11 less per unit than the current component.
Selling price will be increased from £1.43 to £1.45
Fixed selling and distribution costs will reduce from £270,000 to £255,000.
Additional investment in assets will be £0.3 million which will be depreciated at £30,000 per annum.

    🫣 I’ve figured the fixed cost part, I’m so silly!

    I added all of the fixed costs:

    fixed production £135000,
    fixed selling and distribution of £255000
    and £30000 depreciation which equals to

    I think I was getting mixed up with the way the question put 0.135 mill so I thought that the the figures were all millions for example, £135,000,000.🫣
