What is the annual percemtage yield(apy) for money invested at an annual rate of

a 4.31 compounded monthly?

b 4.32 compounded quarterly?

Formula or APY = ( 1 + rate/no. of time compounded )^(no. of times compounded ) -1

a) r = 4.31 % ; n=12

APY = ( 1+ 0.0431/12)^12 -1

=0.04396

APY = 4.4 %

b) r = 4.32% ; n = 4

APY = ( 1+ 0.0432/4)^4 -1

= 0.0439

APY = 4.39%
