On melissa's 6th birthday, she gets a $2000 cd that earns 3% interest,

compounded semiannually. if the cd matures on her 13th birthday, how much

money will be available?

$ 2463.51 will be available.

Step-by-step explanation:

Since, the amount formula in compound interest,

Where,

P = principal amount,

r = annual interest,

n = number of compounding periods,

t = number of years

We have,

P = $ 2000,

r = 3% = 0.03,

Number of years from 6th birthday to 13th birthday , t = 7 years,

n = 2 ( semiannual in a year ),

Hence, the final amount of CD,

probability for j is 1/4

while

a is 1/6
