Answer: $15966.08

Step-by-step explanation:

The formula to calculate the compound amount is given by :-

[tex]A=P(1+r)^t[/tex]

, where P = initial deposit amount.

Time = Time period .

r= Rate of interest in decimal  (compounded once per year)

Given : P= $  12000

r= 7.4 percent =0.074

t= 4 years

Then, the compound amount after 4 years :

[tex]A=12000(1+0.074)^{4}\\\\=12000(1.074)^4=12000(1.33050688258)\\\\=15966.082591\approx15966.08[/tex]

Hence, compound amount after 4 years = $15966.08
