Final answer:
The interest from a $5,000 loan after three years at a 6% interest rate is $900. The interest rate on a $10,000 loan that yielded $500 of interest over five years is 1%.
Step-by-step explanation:
To calculate the total amount of interest from a $5,000 loan after three years with a simple interest rate of 6%, you would use the formula for simple interest which is Interest = Principal × rate × time. In this case, the principal is $5,000, the rate is 6%, or 0.06, and the time is 3 years.
The calculation would be as follows:
- Interest = $5,000 × 0.06 × 3
- Interest = $300 × 3
- Interest = $900
Thus, the total amount of interest from the loan would be $900.
To find the interest rate charged on a $10,000 loan that generated $500 in simple interest over five years, the formula is rearranged to solve for the rate:
Interest = Principal × rate × time
$500 = $10,000 × rate × 5 years
$500 = $50,000 × rate
rate = $500 / $50,000
rate = 0.01 or 1%
The interest rate charged would therefore be 1%.
