Answer:
Option B $128700
Step-by-step explanation:
The amortization can be calculated using the following formula:
Amortization for the Year = Assets Value * (Turquoise Extracted / Total Turquoise)
Amortization for the Year = $429,000 * (1950/6,500) = $128,700
The method used is depletioning method because it seems that the company will extract all of the turquoise within the 3.33 year time (6500/1950), which is within the 5 years duration for which the right to extract the turquoise is purchaseed. Otherwise the straigth line method would had be used here.
