Answer:

Step-by-step explanation:

Rate of interest is 5%.

Time =3years

Amount =$852

Then, we need to find P

Generally compound interest is given as

A=P(1+r/n)^nt

A=final amount

P=initial principal balance

r=interest rate

n=number of times interest applied per time period=12

t=number of time periods elapsed

A=P(1+r/n)^nt

852=P(1+0.05/12)^(12×5)

852=P(1+0.004167)^60

852=P(1.004167)^60

852=1.2834P

Then, P=852/1.2834

P=$663.88

Then the principal amount invested is $663.88

Approximately $664
