Answer:
material L should be sold for at least $3.80 per kg
Step-by-step explanation:
alternative 1, sell material L at scrap value:
35,800 kg x $1.67 = $59,786
alternative 2, process material L and use it to produce Q08C:
processing costs = 35,800 x $0.78 = $27,924
modified L will replace 17,900 of another material that is worth 17,900 x $9.15 = $163,785
net additional income = $163,785 - $27,924 = $135,861
alternative 2 generates the highest additional income = $135,861 / 35,800 = $3.795 per kg.
the minimum acceptable price ≥ to the additional revenue generated by alternative 2, therefore, material L should be sold for at least $3.80 per kg
