Answer:
$35,000
Step-by-step explanation:
The computation of total amount that should be debited to patents is shown below:-
The costs of research and development are incurred in the time in which those costs are incurred and not capitalized.
Total amount that should be debited to patents = Patent granted + Legal fees paid
= $20,000 + $15,000
= $35,000
Therefore for computing the total amount that should be debited to patents we simply added patents granted and legal fees paid.
