Q
Q: If a sum of money is invested at a simple interest rate of 6% per annum, how much interest will be earned on a principal of $8000 after 4 years? (1920)
Solution: Using SI = PRT, SI = 8000 * 0.06 * 4 = $1920.
Steps: 7
Step 1: Identify the principal amount (P). In this case, P = $8000.
Step 2: Identify the interest rate (R). Here, R = 6%, which can be written as a decimal: 0.06.
Step 3: Identify the time period (T). In this case, T = 4 years.
Step 4: Use the simple interest formula: SI = PRT.
Step 5: Substitute the values into the formula: SI = 8000 * 0.06 * 4.
Step 6: Calculate the interest: 8000 * 0.06 = 480, then 480 * 4 = 1920.
Step 7: The total interest earned after 4 years is $1920.
