Answer:
$3,000,000
Explanation:
Short term debt: The short term debt is those debts that are due for a less period i.e less than 12 months or one year. It is shown under the current liabilities on the balance sheet side.
In the question, it is given that the $3,000,000 note payable is mature on March 15, 2018, and we record the same on December 31, 2017 balance sheet. If we see the time period between these two dates so it will be less than 12 months. That's why we consider as a total short term debt
