Given the acquisition cost of product ALPHA is $34, the net realizable value for product(replacement cost) for product ALPHA is $29.50, what is the proper per unit inventory price for product ALPHA?

a) 34

b) 31

c) 29.50

d) 33.50

I thought the answer was 33.50 because the historical cost is 34 and the net realizable value (ceiling) is 33.50. So I thought the lower cost would be 33.50. What am i doing wrong??
