(b) five​-year investment​ period?
(c) eight-year investment​ period?
(d) twenty-year investment​ period?

Answer 1

Answer:

The maturity value of certificate of deposit(CD) would be:

A = P $(1\ +\ r)^{n}$

wherein, A= Amount

              P= Principal

              r= rate of interest compounded annually

              n= no of years to maturity

(a) two year investment plan:

   $6000 (1 + .05) (1 + .05) = $6615

(b) five year investment plan:

= $6000 $(1\ +\ .05)^{5}$ = 6000 (1.2763) = $7657

(c) eight year investment plan:

= $6000 $(1\ +\ .05)^{8}$ = $6000(1.4774) = $8865 approx.

(d) twenty year investment = $6000 $(1\ +\ .05)^{20}$ = $6000 (2.6533) = $15,920 approx
