Answer:
Date Account Title Debit Credit
Nov.1 2021 Cash $80,900,000
Notes Payable $80,900,000
When the note is issued, Ontario resources gained $80.9 million in cash so the Cash account needs to be debited to reflect this.
The Notes Payable account will be credited for the same amount because credit balances like liabilities - which is what a note is - are credited when they increase.
