Step 1: Identify the formula for calculating the monthly payment for a loan. The formula is: \( M = \frac{P \cdot r \cdot (1 + r)^n}{(1 + r)^n - 1} \), where \( M \) is the monthly payment, \( P \) is the loan principal, \( r \) is the monthly interest rate, and \( n \) is the total number of payments.
Step 2: Convert the annual interest rate to a monthly interest rate. Divide the annual interest rate (8\%) by 12 months: \( r = \frac{0.08}{12} \).
Step 3: Calculate the total number of payments. Multiply the number of years (5 years) by 12 months per year: \( n = 5 \cdot 12 \).
Step 4: Substitute the values into the formula. Use \( P = 20000 \), \( r \) (monthly interest rate from Step 2), and \( n \) (total number of payments from Step 3) in the formula \( M = \frac{P \cdot r \cdot (1 + r)^n}{(1 + r)^n - 1} \).
Step 5: Simplify the formula step by step to calculate the monthly payment. Ensure all calculations are performed accurately, including exponentiation and division.
