Question 21 • Advanced Financial Algebra
With annual compounding, the investment grows to $4,000(1.035)^4 after 4 years, which is about $4,590.09. For simple interest to reach the same amount, its rate must satisfy $4,000(1+4r)=$4,590.09, giving r≈0.03688, or 3.688%. Therefore, the matching rate is 3.688% simple interest.
