in the following ordinary annuity interest is compounded with each payment and the payment is made at the end of the compounding
RSB [31]

Answer: $59313.58

Step-by-step explanation:

Formula to find the accumulated amount of the annuity is given by :-

FV=A(\frac{(1+\frac{r}{m})^{mt})-1}{\frac{r}{m}})

, where A is the annuity payment deposit, r is annual interest rate , t is time in years and m is number of periods.

Given : m= $2000 ; m= 1   [∵ its annual] ;   t= 10 years ;   r= 0.06

Now substitute all these value in the formula , we get

FV=(4500)(\frac{(1+\frac{0.06}{1})^{1\times10})-1}{\frac{0.06}{1}})

⇒ FV=(4500)(\frac{(1.06)^{10})-1}{0.06})

⇒ FV=(4500)(\frac{0.79084769654}{0.06})

⇒ FV=(4500)(13.1807949423)

⇒ FV=59313.5772407\approx59313.58 \ \ \text{ [Rounded to the nearest cent]}

Hence, the accumulated amount of the annuity= $59313.58
