Answer:
$3316 should be invested.
Explanation:
Since, the amount formula in compound interest is,
![A=P(1+r)^t](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mx7m27cl3u5582uaxzowc38y4tzzboesz2.png)
Where, P is the principal amount,
r is the rate per period,
t is the time in years,
Here,
A = $ 60,000,
r = 10.5% = 0.105
t = 29 years,
By substituting value,
![60000=P(1+0.105)^(29)](https://img.qammunity.org/2020/formulas/mathematics/college/zvu9koe6m3h50qv0ucdpj4kl8bcvjre1ge.png)
![P=(60000)/(1.105^(29))=\$3316.23415377\approx \$3316](https://img.qammunity.org/2020/formulas/mathematics/college/cstwb2mvpf57ztpyi3s8j7bzdz3urrakjy.png)
Hence, $ 3316 should be invested.
