How much money should I invest at an annually compounded interest rate of 5% so that I have $500,000 in ten years? Express your answer as a dollar value rounded to the nearest cent.
FV = PV x [ 1 + R]^N
500,000 =PV x 1.05^10
500,000 =PV x 1.62889462677744140625
PV =500,000 / 1.6288946............
PV =$306,956.63
500000 = A( 1 + .05)^ 10 divide both sides by ( 1 + .05)^10
500000/ ( 1 + .05)^10 = A ≈ $306956.63
