Answer:
100% equity financing from personal investments is better
Step-by-step explanation:
100% equity financing option.
Expected annual return on the project = $30,000
Lost investment opportunity = 8.5% * 250,000 = $21,250.
Therefore incremental return from 100% equity financing option = $30,000 - $21,250 = $8,750 annually.
60% debt and 40% equity financing option.
Expected annual return on the project = $30,000
Lost investment opportunity = 8.5% * 40% * 250,000 = $8,500.
Interest rate on debt = 9% * 60% * 250,000 = $13,500.
Therefore incremental return = $30,000 - $8,500 - $13,500 = $8,000 annually.
Since the 100% financing gives a higher return than the debt-equity option, the 100% financing option is better.
