Answer:

c) multiplying the principal by the interest rate and the time.

Step-by-step explanation:

The interest is calculated by product of the principal amount and the interest rate and the time.

And if we want the total future value that the person has to pay then add the principal amount to the interest.

Amount=P+P*R*T

Amount=P(1+RT)

Hence we conclude that the answer is option c).
