Shota invests $2000 in a certificate of deposit that earns 2% in interest each year.Write a function that gives the total v(t) i
brilliants [131]

Answer:

The correct answer is v(t) = (principal × time × 0.02) if calculated simply and v(t) = Principal × ( 1.02) ^ {time} where v(t) is the interest after t years .

Step-by-step explanation:

Principal amount invested by Shota is $2000.

Interest is earned at 2% per year.

Time for which the principal is invested is t years.

Therefore let the total interest be v(t) dollars in t years.

Case 1: Simple Interest.

v(t) = (principal × time × \frac{r}{100} ) = (2000 × t × 0.02) = 40t

Case 2: Compound Interest.

v(t) = Principal × ( 1+ \frac{r}{100}) ^ {t} - Principal =  2000 × ( 1.02) ^ {t} - 2000.
