[Answered] Background Info: Tom finds a second personal loan option. This loan would also require him to repay the principal in one lump sum after three years. Loan Option B Principal: $89,000 Type of Interest: Compound Interest Interest Rate: 8% Rate of Accrual: Once per year Use the formula for annual compound interest.
