Answer:
$30,000
Explanation:
The computation of the royalty revenue reported is shown below:
= Patent-related sales for the year × given percentage
= $300,000 × 10%
= $30,000
The revenue is recognized when it is earned or realized so only $30,000 is to be reported as the royalty revenue
The remaining amount i.e $20,000 would be treated as an unearned royalty revenue
