Respuesta :

Answer:

$81.03

Step-by-step explanation:

Given

[tex]n = 1[/tex] --- annually

[tex]t =3[/tex] --- time

[tex]r = 5\%[/tex] --- rate

[tex]PV = \$70[/tex] ---- Present value

Required

The future value

This is calculated as:

[tex]FV = PV * (1 + \frac{r}{n})^{nt}[/tex]

This gives:

[tex]FV = 70 * (1 + \frac{5\%}{1})^{1*3}[/tex]

[tex]FV = 70 * (1 + 5\%)^3[/tex]

[tex]FV = 70 * (1.05)^3[/tex]

[tex]FV = 70 * 1.157625[/tex]

[tex]FV = 81.03375[/tex]

The future value to the nearest cent is: $81.03
