Answer:
$1445.11
Step-by-step explanation:
The formula to use would be:
![F=P(1+r)^t](https://tex.z-dn.net/?f=F%3DP%281%2Br%29%5Et)
Where
F is the future amount (what we want to find)
P is the present (principal) amount (this is 400)
r is the rate of interest, monthly (1.8% or 0.018)
t is the time in months (6 years = 6 * 12 = 72)
Now substituting, we get:
![F=P(1+r)^t\\F=400(1+0.018)^{72}\\F = 400(1.018)^{72}\\F=1445.11](https://tex.z-dn.net/?f=F%3DP%281%2Br%29%5Et%5C%5CF%3D400%281%2B0.018%29%5E%7B72%7D%5C%5CF%20%3D%20400%281.018%29%5E%7B72%7D%5C%5CF%3D1445.11)
After 6 years, the CD will be worth $1445.11
