Answer

The annual simple interest rate is approximately 4.1%.

Solution

We are given: • Principal, P = $8,250 • Maturity value, M = $8,363.50 • Loan period, t = 4 months = 4/12 = 1/3 year For simple interest, the maturity value is given by:   M = P(1 + r × t) where r is the annual interest rate (in decimal form). Step 1: Set up the equation:   8,363.50 = 8,250(1 + r × (1/3)) Step 2: Solve for r:   Divide both sides by 8,250:     1 + (r/3) = 8,363.50 / 8,250 Calculate the division:   8,363.50 / 8,250 = 1.01376 (approximately) Thus,   1 + (r/3) ≈ 1.01376 Subtract 1 from both sides:   r/3 ≈ 0.01376 Multiply both sides by 3:   r ≈ 0.01376 × 3 = 0.04128 Step 3: Convert to a percentage:   r ≈ 0.04128 × 100 ≈ 4.1% Rounded to one decimal place, the annual simple interest rate on this loan is approximately 4.1%.

To find the annual simple interest rate, we can use the formula for simple interest: \( I = P \times r \times t \), where \( I \) is the interest earned, \( P \) is the principal amount, \( r \) is the interest rate, and \( t \) is the time in years. First, calculate the interest earned: \( I = 8,363.50 - 8,250 = 113.50 \). Next, convert the loan duration to years: \( t = \frac{4}{12} = \frac{1}{3} \) year. Now plug in the values into the formula to solve for \( r \): \( 113.50 = 8,250 \times r \times \frac{1}{3} \). Rearranging gives: \( r = \frac{113.50 \times 3}{8,250} = \frac{340.50}{8,250} \approx 0.0412 \) or \( 4.12\% \). Now, rounding to one decimal place gives us an annual simple interest rate of \( 4.1\% \). And there you have it! The annual simple interest rate for this loan is \( 4.1\% \). Happy calculating!
