Questions & Step-by-Step Solutions
A loan of $5000 is taken at a compound interest rate of 5% per annum. What will be the total amount to be paid after 3 years?
Step 1: Identify the principal amount (P), which is the initial loan amount. Here, P = $5000.
Step 2: Identify the annual interest rate (r). Here, r = 5%, which is 0.05 in decimal form.
Step 3: Identify the time period (t) in years. Here, t = 3 years.
Step 4: Use the compound interest formula A = P(1 + r)^t to calculate the total amount (A).
Step 5: Substitute the values into the formula: A = 5000(1 + 0.05)^3.
Step 6: Calculate (1 + 0.05) = 1.05.
Step 7: Raise 1.05 to the power of 3: (1.05)^3 = 1.157625.
Step 8: Multiply the principal amount by this result: A = 5000 * 1.157625.
Step 9: Calculate the total amount: A = 5788.125.
Step 10: Round the total amount to two decimal places: A = $5788.13.
