Answer:
A. $13,000
Step-by-step explanation:
The computation of the royalty revenue is shown below:
= Estimated sales of the trademarked items × given percentage + September 2005 royalties received
= $30,000 ×15% + $8,500
= $4,500 + $8,500
= $13,000
For the first half, the royalty would be $8,500 and the second half it would depend on the estimated sales which we computed above
