Answer:
Option (c) is correct.
Explanation:
Given that,
Present value = $108,000
Future value = $245,000
Time period, n = 15 years
[tex]Present\ value = Future\ value\times(\frac{1}{1+i} )^{n}[/tex]
[tex]108,000=245,000\times(\frac{1}{1+i} )^{15}[/tex]
[tex]0.4408=(\frac{1}{1+i})^{15}[/tex]
[tex]0.9469 =\frac{1}{1+i}[/tex]
0.9469 + 0.9469i = 1
0.9469i = 1 - 0.9469
0.9469i = 0.0531
i = 0.0531 ÷ 0.9469
i = 0.05607 or 5.61%
Therefore, the rate of Interest must you earn to cover the cost of your child's college education is 5.61%.
