8) $14,000 invested at 7% compounded semiannually after a period of 12 yearsF) $31,530.68G) $17.966.6H) $30,885.60J) $31,966.60

Sagot :

Consider that the amount is given by,

[tex]A=P(1+r)^n[/tex]

Here, 'P' is the principal, 'n' is the number of compounding periods, 'r' is the effective rate of interest per period.

Given that compounding is done semiannually i.e. twice a year, so the number of periods in 12 years will be 24,

[tex]n=2\times12=24[/tex]

The effective rate of interest is given by,

[tex]r=\frac{7}{2\times100}=0.035[/tex]

Substitute the values and solve for the amount as follows,

[tex]\begin{gathered} A=14000(1+0.035)^{24} \\ A=14000\times2.28 \\ A=31966.60 \end{gathered}[/tex]

Thus, the required amount will be $31966.60

Therefore, option J is the correct choice.
