A compound investment to yield $820, help?

Posted at: 2014-12-05 
Apply compound interest formula and find out. The formula :

A = P ( 1 + r )^n 820 = P ( 1+.05 ) ^3 =

P ( 1.05 ) (1.05) (1.05) =820

P x 1.15 = 820

P = 820 / 1.15 = 713

Yes

Use formula:

A=P(1+R)^t

A=$820

R=5%

t=3 years

P=?

Put in the formula,

P=713

I'm thinking about investing money at 5%, compounded continuously, for three years until I can yield $820; but how much money will yield this goal?

A step-by-step explanation would be greatly appreciated, thanks.
