Answer:
- Retire Long Term debt at $0
- Issue Long Term Debt at $6,000
Step-by-step explanation:
If you elect to both retire the $6,000 in long term debt and also issue long term debt of the same amount, your cash balance would be -$3,000 which is unhealthy.
What you should do therefore, is to retire no long term debt while still issuing the long term debt of $6,000 to pay for the investment in plant improvement. This will leave you with a cash balance of $3,000 which is healthy enough.
