Answer:
$658,000
Explanation:
According to the scenario, computation of the given data are as follows:
Granite Enterprises Patent acquired = $3.4 million
Used years = 5 years
Rocky corporation purchase after 5 years = $110,000
So, we can calculate the Granite's patent amortisation by using following formula:
Granite's patent amortisation = ($3,400,000 - $110,000) ÷ 5
= $3,290,000 ÷ 5
= $658,000
