Answer:

Second option:



\boxed{ \$6,671.67}

Explanation:

The equation for the amount accrued at 5.4% interest compounded semi-annually(twice a year) for an initial investment P for t years is already given:


A = P\left(1 + (0.054)/(2)\right)^(2t)

Plug in
P = $3000
t = 15 years


A = 3000\left(1 + 0.054\right)^(2\cdot 15)\\\\A = 3000(1 + 0.027)^(30)\\\\A = 3000(1.027)^(30)\\\\A = 3000 (2.22389)\\\\A = \$6,671.67
This is the second option
