Judith has \$70 in a savings account that earns 5% interest , compounded annually .
Firlakuza [10]

Answer:

$81.03

Step-by-step explanation:

Given

n = 1 --- annually

t =3 --- time

r = 5\% --- rate

PV = \$70 ---- Present value

Required

The future value

This is calculated as:

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

This gives:

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

FV = 70 * (1 + 5\%)^3

FV = 70 * (1.05)^3

FV = 70 * 1.157625

FV = 81.03375

<em>The future value to the nearest cent is: $81.03</em>
