A = 7000(1+0.1/4)4(5)
    = 7000(1.02500)²⁰
    = D
The answer is D.

Hope this helps :)

Initial Deposit = $7000

It means P= $7000

rate of interest = 10%

So , r = 0.10

compounded quarterly , so  n = 4

and we have to find the amount after 5 years , So t = 5


Now the formula we use here is

[tex]A= P(1+\frac{r}{n} )^{nt}[/tex]

[tex]A= 7000(1+\frac{0.10}{4} )^{(4)(5)}[/tex]

[tex]A= 7000(1.025 )^{(20)}[/tex]

[tex]A= 7000(1.63861644029)[/tex]

[tex]A= 11470.315[/tex]


So amount after 5 years = $11470.315
