Respuesta :

Answer:

a) = $10,896.71

b) = $11,768.45

Explanation:

The question is divided into 2 parts

Part a) Amount in the account today

The formula to use is as follows:

FV of Annuity= P(1+r)∧n - 1)/r

P= Periodic Payment = $450

r= Rate of each period= 8%

n= the number of periods= 14

The account today is as follows:

FV = 450 x (1+0.08)∧14-1]/0.08

= $10,896.71

Part b) The formula to use is as follows:

FV = Future value = (1+r) * P * [ (1+r)n -1] / r

P= Periodic Payment = $450

r= Rate of each period= 8%

n= the number of periods= 14

= Fv= (1+0.08) * 450 * [ (1+0.08)^14 - 1] / 0.08

= $11,768.45
