Final answer:
The simple interest on the $675 loan for 75 days is approximately $50, and the interest rate is approximately 14.18%.
Step-by-step explanation:
To find the simple interest, we can use the formula:
Interest = Principal × Rate × Time
For this problem, the principal (loan amount) is $675, the interest is $725 - $675 = $50, and the time is 75 days. We need to convert the time to years by dividing by 365:
Time = 75 days ÷ 365 days/year ≈ 0.2055 years
Plugging in these values, we get:
Interest = $675 × Rate × 0.2055 = $50
Solving for the interest rate, we have:
Rate = $50 ÷ ($675 × 0.2055) ≈ 0.1418, or 14.18%
The simple interest on the $675 loan for 75 days is approximately $50, and the interest rate is approximately 14.18%.
