Answer:
Explanation:
a. To calculate the interest for $20,000 at a 3% interest rate over 3 years, we use the formula: Interest = Principal × Rate × Time.
So, the interest would be $20,000 × 0.03 × 3 = $1,800.
b. For $25,000 at a 12% interest rate over 5 months, we need to convert the time to years. 5 months is 5/12 of a year.
Using the same formula, the interest would be $25,000 × 0.12 × (5/12) = $1,250.
c. For $9,500 at an 18% interest rate over 80 days, we also need to convert the time to years. 80 days is 80/360 of a year.
Applying the formula, the interest would be $9,500 × 0.18 × (80/360) = $380.
