Final answer:
The interest rate on Nora's loan is 5%.
Step-by-step explanation:
To find the interest rate, we can use the formula:
Interest = Principal × rate × time
Given that Nora borrowed $5000 and the interest paid over 3 years is $750, we can plug these values into the formula:
$750 = $5000 × rate × 3
Solving for rate, we get:
Rate = $750 / ($5000 × 3) = 0.05 = 5%
Therefore, the interest rate is 5%.
