Question

Write an expression that would calculated the value of the following account after 14 years: $8100 is invested at an APR of 4.8% compounded semiannually (twice per year).

Answer 1

Answer:

  $8100·1.024^28

Step-by-step explanation:

The future value formula is ...

  FV = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual interest rate, n is the number of times per year interest is compounded and t is the number of years. Putting the given numbers in place of the corresponding variables gives the expression you want:

  FV = $8100(1 +.048/2)^(2·14)

  FV = $8100·1.024^28 . . . . . simplified
