If a person lnvests $120 at 8% annual interest, find the approximate value of the investment at the end of 5 years
Pie

Answer:

$176.3193692 or $176.32 (rounded to two decimal places)

Step-by-step explanation:

It is a compound interest, which means the interest accumulates on an initial amount each period.

The formula is A=P(1+R)^n

A= the total amount P=initial amount      R=rate   n=time (years)

P=$120   Rate= 8% or 0.08 (decimal)  n=5 (years)

A=120 (1+0.08)^2

A=120 (1.469328077)

A= 176.3193692
