Answer:

[tex]\$10272.17[/tex]

Step-by-step explanation:

Since it is compounded continuously, we will use:

[tex]A=A_0 \cdot e^{k t}[/tex]

[tex]A_0[/tex] is the amount invested.

[tex]k[/tex] is the rate.

[tex]t[/tex] is the number of years you let the money sit.

[tex]A[/tex] is the future amount after the [tex]t[/tex] years that has been accumulated.

(Note:

I'm going to write [tex]r=4%[/tex] as a decimal. [tex]r=\frac{4}{100}=0.04[/tex].)

[tex]A=5000 \cdot e^{0.04 \cdot 18}[/tex]

[tex]A=5000 \cdot e^{0.72}[/tex]

[tex]A=5000 \cdot 2.0544332[/tex] (approximated)

[tex]A=10272.16605[/tex] (approximated)

To the nearest cent this is [tex]\$10272.17[/tex].
