Greg deposited $4000 into an account with a 9.8% annual interest rate, compounded semiannually. Assuming that no withdrawals are
Dovator [93]

The number of years it would take $4000 to grow to $4616 is 2.92 years.

<h3>How many years would it take the investment to have a value of $4616?</h3>

When an amount earns compound interest compounded semi annually, it means that both the amount invested and the interest accrued increases in value twice yearly.

Number of years = (In FV / PV) / r

  • r = 9.8/2 = 4.90%
  • FV = future value = 4616
  • PV = present value = 4000

(In 4616 / 4000) / 0.049 = 2.92 years

Sample Response: There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.
