Answer:
$350,000
Explanation:
total intangible assets:
Copyrights $2,000,000 (amortizable)
Goodwill $4,500,000 (not amortizable)
Patents $1,500,000 (amortizable)
Trademarks $1,000,000 (not amortizable)
since you can only amortize copyrights and patents, total amortization expense for the year = ($2,000,000 + $1,500,000) x 10% = $350,000
both trademarks and goodwill can be impaired though (impairment costs are evaluated on a yearly basis).
