Total = 200 * (1 + .04 / 4) ^ 4*4
Total = 200 * (1 + .01) ^ 16
The answer is C

Answer:

C. [tex]200(1+0.01)^{16}[/tex]

Step-by-step explanation:

We are given that,

Initial investment, P = $200

Rate of interest, r = 4% = 0.04

Time period, t = 4

It is required to find the formula for the money which is compounded quarterly.

The compound interest is given by [tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Substituting the value, we have,

[tex]A=200(1+\frac{0.04}{4})^{4\times 4}[/tex]

i.e. [tex]A=200(1+0.01)^{16}[/tex]

Hence, the formula for the money after 4 years is [tex]200(1+0.01)^{16}[/tex].
