o $ 9,725.40
o none of the above

$13,52.60

Step-by-step explanation:

The formula to apply is

where

A= amount of money at the end

P=the amount of money to invest, principal

r=rate of interest in decimal

n=number of compoundings per year

t=time in years

Given that;

t=4 years

A=$18000

P=?

r=0.08

n=2

Substitute values in the formula

Divide both sides by 1.36856905041 to remain with P

P=$13152.56

i would pic false cause it goes down towards negative
