答案

a)
Effective rate = (Interest/usable Funds) x (360/Loan Period(days))
Effective interest rate= (0.034/0.966) x ( 360/360) = 3.5197%
b)
Effective annual rate = [ discount / (100%-discount) ] x [ 360 / (credit period - discount period) ]
=[ 3.4%/ (100%- 3.4%)] x [ 360 / (32-1) ]
=(0.034/0.966) x (360/31)
=40.874%
