Final answer:
Irving should proceed with the project because the expected rate of return is higher than the interest rate on the loan.
Step-by-step explanation:
Irving should proceed with the project because the expected rate of return (15%) is higher than the interest rate on the loan (12%). This means that Irving has the potential to earn a higher return on his investment than the cost of borrowing the money. Here's the calculation:
- Expected Rate of Return - Loan Interest Rate = Net Return
- 15% - 12% = 3%
Since the net return is positive (3%), Irving should proceed with the project.
