Respuesta :
Approximately the principal that is needed to be placed to accumulate the given amount is $23,377.
The given parameters:
- Interest rate , I = 3.575%
- Amount accumulated, A = $68,000
- Time period, t = 30 years
- The number cycles, n = 4
What is compound interest?
Compound interest is the accumulated interest over a given period of investment.
The principle amount is determined from compound interest formula as shown below;
[tex]A = P( 1 + \frac{r}{n} )^{nt}\\\\68,000 = P (1 + \frac{0.03575}{4} )^{(4 \times 30)}\\\\68,000 = P(1.00894)^{120}\\\\P = \frac{68,000}{(1.00894)^{120}} \\\\P = \$23,370.5 \[/tex]
Thus, approximately the principal that is needed to be placed to accumulate the given amount is $23,377.
