Answer and Explanation:
The computation of the unit values that used for the products 1 and 2 is shown below
But before that the following formulas are there
Ceiling
= Net realizable value = Selling price - predicted dispose cost
Floor = Net realizable value - Normal profit Margin
Market value = Middle of Ceiling, Floor, Replacement cost
Now
Particulars Product#1 Product#2
Historical cost $8 $19
Ceiling $19 ($21 -$2) $28 ($33- $5)
Floor $12.7 $18.1
[$19 - ($21 × 30%)] [$28 - ($33 × 30%)]
Replacement cost $12 $12
Market $12.7 $18.1
Lower of cost or market $8 $18.1
