Answer:
See below.
Explanation:
Congrats on your first question.
I see a comparison problem here after some simple math.
They paid 15,750 for the inventory some time in the past.
It's worth 21,000 now (scrap value).
They got off lucky that it's worth more as scrap than when it was new product, as that's usually nowhere near the case. So they could sell and realize a profit of 21,000 - 15,750 = 5,350. Not bad.
But there's this other option where they can put 15,750 more into it and sell it for 52,500.
How do we decide if that's better?
We just need to add the original cost with this additional cost, then sell it for 52,500 and see what the profit would be.
15,750 + 15,750 = 31,500 total cost
Now find the profit if they sell:
52,500 - 31,500 = 21,000
Which one would you do? That's your answer.
