Answer:
The value of Ted's annuity at the end of eight years is $5318.3138.
Explanation:
Given : Ted Williams made deposits of $500 at the end of each year for eight years. The rate is 8% compounded annually.
To find : The value of Ted's annuity at the end of eight years ?
Solution :
The future value of an ordinary annuity is given by,
![FV=C[((1+i)^n-1)/(i)]](https://img.qammunity.org/2020/formulas/mathematics/high-school/zjqsnlxkt2mognle44uzg2r96u4bqsvv4s.png)
Where,
C is deposit amount C=$500
n is the number of payments n=8
i is the interest rate i=8%=0.08
Substitute the value in the formula,
![FV=500[((1+0.08)^(8)-1)/(0.08)]](https://img.qammunity.org/2020/formulas/mathematics/high-school/9s5fr5oxidgzoqhku60s6gajlnhyk9x3qb.png)
![FV=500[((1.08)^(8)-1)/(0.08)]](https://img.qammunity.org/2020/formulas/mathematics/high-school/pznga0x2rjo7uyin98kg8g5mx6su8gdo3d.png)
![FV=500[(0.8509)/(0.08)]](https://img.qammunity.org/2020/formulas/mathematics/high-school/zpct1l37ly8raynmzelns49ctntfa1gstk.png)
![FV=500[10.6366]](https://img.qammunity.org/2020/formulas/mathematics/high-school/3eaadbkbnvjaio31u357s19olsl66nw9fm.png)

Therefore, the value of Ted's annuity at the end of eight years is $5318.3138.
