What initial investment at 7 percent compounded semi-annually for 7 years will accumulate to $9,000? Round answer to two decimal places.?

9000 = P(1 + .07/2)^(2 * 7)

9000 = P * 1.035^14

9000 / 1.035^14 = P

5560.036112490051793640948910059 = P

$5,560.04

hint:
use the compound interest formula:
A=P(1+i/n)^(nt)
where n=number of times per year interest is compounded.
t=number of years
i=interest (decimal)
P=initial investment
A=future value.

P*1.07^7 = 9000
P = 9000/1.07^7 = $5604.75
