Answer:
The lower- of- market- or cost for the item is $21
Explanation:
In the lower of cost or market, the market begins at the replacement cost which is $20, which is then limited or restricted to a ceiling and a floor.
The ceiling is computed as:
Ceiling = Selling price - Completion cost
where
selling price is $30
Completion cost is $2
Putting the values above:
Ceiling = $30 - $2
Ceiling = $28
Computing the floor as:
Floor = Ceiling - Normal profit margin
Floor = $28 - $7
Floor = $21
As the market cannot be lower than the floor which is $21. Therefore, the lower of cost which is $26 and the market which is $21. But have to take lower. So, it is $21.
