Answer:
The balance will be $7,577.03.
Step-by-step explanation:
The compound interest formula is given by:
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.
In this problem, we have that:
[tex]P = 7000, r = 0.04[/tex]
Semianually means twice a year, so [tex]n = 2[/tex]
We want to find A when [tex]t = 2[/tex].
So
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A = 7000(1 + \frac{0.04}{2})^{2*2}[/tex]
[tex]A = 7577.03[/tex]
The balance will be $7,577.03.
