Answer:
The total amount that will be debited to the patents account on July 31, 2017 will be $35,000.
Explanation:
The amount of $150,000 will not be included in the patents account because this patent was developed by the Martha beyerlein company not purchased from any other firm , so the cost incurred here will be debited to the research and development account. And only the $35,000 that was paid for legal fees will be debited to the patents account.
