Sarah invested $5000 at a simple interest rate of 10% per annum. Find the amount she will receive at the end of three years.

Correct option is D

Given:
Principal (P) = $5000
Rate of interest (R) = 10% per annum
Time (T) = 3 years
Formula Used:

$$SI = \frac{P \times R \times T}{100}$$​

Amount = Principal + Simple Interest
Solution:

$$\\SI = \frac{5000 \times 10 \times 3}{100} = 1500 \\\text{Amount} = P + SI = 5000 + 1500 = 6500 \\$$​
