Question 930264
take 132.56 and multiply by 36 = 4768.56
subtract 4000 from 4768.56 = 768.56 of interest over 3 years
interest = principal * simple interest rate * (36/12)
simple interest rate = interest / (principal * 3)
simple interest rate = 768.56 / (4000 * 3) = 0.064046667 approx 6% per annum and 19% (3*0.064046667) over the three years of the loan
