Answer:
correct answer is a. yes
Explanation:
given data
spent = $1000
estimates of sales = $2000
total sales = $800
hot-dog stand for another = $300
solution
we already spent here $1000 and assuming it is not recover
so If you do nothing it will be sunk cost in future
and
when we spend $300 another and earn $800
so we make here = $1000 + $300 - $800 = $500
so we can lose $500
so here lose $500 is better than lose $1000
so correct answer is a. yes
