Econ ex 2 pg 512

At the risk of asking a stupid question, I am getting answer A every time I do this but book says B, what am I doing wrong??? Driving me nuts

Well… hard to tell if you dont show us what you are doing. I mean you have the full formula and plugging in all the numbers gives you -0.0254. Are you doing the Day Count Convention correctly?

HA, I’m literally plugging in the numbers exactly as shown and calc is spitting out -.0346…I dunno

Okay im retarded…In the denominator i was using (1+I(i,d))*.75 when it was 1+(I,d*.75)
