I do not know how to go from my last step and find an answer. This is what I have so far, but do not know how to go from here. It is very confusing to me. 1700=1500(1+ r/360)^360 x 4 1700=1500(1+ r/360)^1280 ln(1+r/360)^1280=ln(17/15) 1280ln(1+r/360)=ln(17/15) ln(1+r/360)=ln(17/15) all over 1280 =1/1280ln(17/15) =ln(17/15)^1/1280 r=360[((17/15)^1/1280)-1] This is where I do not understand how to go. I have tried to divide 17 by 15 giving me 1.13, then taking that to the power of 1/1280, giving me 8.9, then subtracting 1, which gives me a -.9991145833. Click here to see answer by stanbon(57361)
